It's definitely "RE4 HD," but I've honestly come to appreciate that. The controls took a while to get used to, but at this point they feel as natural as any other game. Doesn't mean I agree with the design, but the action itself made it worth adapting to (similar to Killzone 2, in my opinion). It took a while for that action to become that satisfying, though.
As for Sheva, I'm not having nearly as many problems with her as I thought I would. Of course, I also don't leave her to care for herself unless I really have to, and I was pretty damned annoyed when she got her head sawed off, but I think they did a pretty good job giving you a partner without taking any of the action away from my own character.
Again, though, I'm playing on Normal. I don't think Sheva would be as tolerable on a higher difficulty setting.
All of that said, I do think it's plainly inferior to Gears of War 2, and the fact that there are even grounds to make that comparison says something about how far Capcom has strayed from the traditional RE format.
