>>7797033The old W figures are alright, if outdated now. W himself has a very limited ab crunch and the wrong joint color on all the non-black elbow and knee joints, those were the main complaints with him. Accel is fun. Skull is fun, but get Skull Crystal, it's the better of the two and has the parts to do either look. Eternal is fine too. All of these have pretty proportionally inaccurate sculpts, but it'll do if you're on a budget.
And now we come to the relatively recently Shinkocchou Seihou SHFs, which were completely revamped redos. Proportions, articulation, and colors are way better, but they will cost you a LOT more, especially since they are out of production and aftermarket prices are a bitch. They made everyone on your list, so you're good there. Eternal in particular is gonna really hurt your wallet.
Here's a comparison of the old and new. Old on right, new on left. It's a substantial improvement if you can afford it.
