I prefer the SS 7x7 over the V cube simply because it doesn't pop. My V cube pops normally around 5 times a solve so it's nice to have a cube that doesn't do that.
Definitely ShengShou. I have serious gripping issues on pillowed cubes.
You should consider buying a Type C WitTwo.. it is without a doubt the best 2x2x2 speedcube out there. It has a nice scratchy feel to it and to lubricant it reacts very well.
That is indeed what I was considering. Have to find out first whether or not I want to use the 2x2 more than I do now, but if so, then I will. Thanks!
After using the V7 for a while, the Shengshou doesn't seem square; it's like it seems hollow.
Anyway, I modified a Shengshou 7x7x7 following the usual mod for 5x5x5s and now it reverse corner cuts. But it also makes more racket and is more likely to pop:
