It's about that time again! Excuse me while I whip this out.
Made a lil more effort in making the comparisons higher quality. Changed the layout a bit, too. I'll eventually go back and redo the older ones I posted to make everything more consistent.
Icons shown belong to their respective half of the comparison. If they're identical, they'll say "identical." If they're different, they won't say anything. Pre-nerf will always be on top. Post-nerf will always be on bottom.
Before we get into it I'd like to thank Capitalist for his very generous donation of Galigord's Rod, Willcrusher, Shen's Censure, and Woe Spreader.
Let's do the thing.
Monk
Hukhrah's Staff: I knew this one was out there based on an old screenshot I found, but never really expected to find it. The overabundance of staves created by Mount Qinkai vanquishes should have long since buried their more ancient counterpart.
Shen's Censure: A surprising find. Hadn't considered this one prior to its discovery, but Capitalist came in clutch. Tip of the hat to you. The colors on this one seem identical to the colors on Hukhrah's. Stats, order and icons are identical.
Incetol's Focus: Harder to farm than The Stonehart and Byzzr's Benediction, makes sense that this was the last of the pre-nerf loops to be found.* The trio is complete! Stats, order and icon are identical.
*There is Feng's Focus, but it uses the base dye color for divine symbol loops and there's no evidence to suggest its stats would change somehow, so I don't believe it will have a pre-nerf version.
Necro
Gordac's Holy Rod: The first of Gordac's pre-nerfs to be found, but the last of the pre-nerf holy rods! As with Incetol's Focus and the loops, there is one other holy rod from Proph/Factions (Ivor's Smiting Rod), but it also uses the base color for holy rods. Until proven otherwise, I don't believe a pre-nerf Ivor Rod exists. This one is interesting in that its confirmation should remove the possibility of different mod orders on pre-nerf wands.
This image (found in the list in the OP) is of the original stats (note the +3 energy instead of the standard +5 now).
The stats nowadays are identical but the colors are different (the usual case). There's no evidence so far that a pre-nerf will have current stats but an old color, so I think it's safe to assume that all pre-nerf Gordac Rods (and any others that may have had this old order) were retroactively updated. Stats, order and icons are identical.
Milthuran's Staff: Not me just casually sneaking in another 3rd version. Unlike the above, old stats but new color is a possibility. I refer to these as 3rd versions as, well, they were the 3rd version of the items to be found. Big brain. Until now, Kepkhet's Refuge and The Stonereaper were the only confirmed 3rd versions. In theory, my Spiritgarden's Repose and Kaolin Accursed Staff are as well, but their normal pre-nerfs haven't been found yet.
That said, if there was any doubt before, all staves with a mod order and color change should have 3 versions. These are more rare than their usual pre-nerf counterpart, as the window for these to have dropped was significantly smaller. Here's the updated comparison of all 3. The 3rd version here is the middle image (with old stats but new color).
Bortak's Bone Cesta: This one follows the same color change as Kole's Gauntlet and is the 2nd (and last) pre-nerf glove skins. Vilnar's Glove uses the base dye for glove gauntlets, and shouldn't have any other changes. It's also the first of Bortak's weapons confirmed. The staff should be out there somewhere... Stats, order and icons are identical.
Woe Spreader: There's a pic of the pre-nerf stats for Siska's Staff in the OP, but this is the first of the four Elliptical Staff greens to be confirmed in game. Siska's and Ssuns' should have a mod and color change, and Ssyn's should just have a color change. Stats and order are identical. Icons are different.
Warrior
Warrior was one of the bigger winners with this update.
The Stonebreaker (Hammer): Slightly more exotic than your typical Pongmei/Dragon Moss fodder, this one boasts a pretty big color change. Stats and order are identical. Icons are different.
The Ugly Stick: This counts as a pre-nerf spiked club, right? Yeah totally. Ugly no more. It's found a loving home. This is another very subtle one, so I added a box to note the difference as well as a drop color comparison to show it more easily. Stats and order are the same. Icons are very slightly different.
Jacqui's Aegis: Objectively less ugly. Who doesn't like shiny things? Stats and order are identical. Icons are different. I believe the only remaining Factions shield that will have a color change is Arrahhsh's Aegis. If you think you might have one, get in touch!
Wing's Axe: The first confirmed pre-nerf axe. There should be one for Razorfin's Axe as well. Wing's sports a small color change on the handle (looks similar to the change on Sskai's Sword). The icon handle is noticeably whiter. Stats and order are identical.
Ele
Ele was the other big winner here and the one I'm most excited about as it's a big nostalgia trip to the birthplace of greens.
The Brimstone: Was super happy to finally get this one. The storm artifact prenerfs have some nice colors. Soulstone/Brimstone are found. Snapjaw's Powerstone should be out there somewhere, and with the same colors as the Brimstone. Have one? Message me! Stats, order and icons are identical.
Brimstone Wand: Yep, the pair is complete. Similar color swap to the Brimstone. Stoked to now have the full Brimstone set (the staff was confirmed earlier this year). Stats, order and icons are identical.
Galigord's Rod: Another vivid color swap. I'm pretty sure this pre-nerf color of this one will match the pre-nerf color of Seacrash's Influence. If you have one you think looks similar, please get in touch. Stats, order and icons are identical.
Flint's Fleshcleaver: Most of the pre-nerf colors are so nice. Why'd they have to go and do us like this? Stats, order and icons are identical.
Mesmer
Wayward Wand (Domination/Inspiration): The 4th of the 5 known pre-nerf Waywards. Just the Illusion/Inspiration is left. All modern green Wayward Wands will have matching attributes in their requirement and mod. Icons and color are identical.
I think it's weird that only these few combos would exist and not, say, Divine/Smiting, among others, as well. Who knows why Anet does what they do. If you have an Illusion/Inspiration one, please reach out!
Willcrusher: Last but not least, another bad boy from Sorrow's Furnace. The skin is sick, just wish the stats were more useful. The base skin (Willcrusher Staff) is undyeable and no color change is seen between these two versions. It does have a pretty obvious mod order swap though.
