I wish I hadn't sold my WS Steve sculpt, I prefer that to the AoU one.
I like both the same. I like TWS soldier sculpt being that it's looking straight on, but I also like the AoU sculpt because the skin hue is a tad lighter than TWS soldier one, which I found matches the tone of the hands more (no biggie, but just something I noticed). The AoU hair has a bit more of a goldish tint, but not by much. They're essentially the same sculpt, so you can't really go wrong with either.
If I HAD to choose one though, I'd probably go with TWS one. As mentioned, the eyes are looking straight on, so I would imagine that makes it a bit more versatile for posing.
