Do you think Reach is prettier?

Maybe it's the art direction, but I was playing Reach last night (still had about 70,000 players online surprisingly) and I felt like Reach was prettier graphically. And frame-rate wise, it felt like Reach was silky smooth where Halo 4 has is kind of jerky in places (could be lag). Someone on the Internet somewhere argued that Halo 4's maps are very minimalist and there's less going on in the environments and less distracting. So if the graphics are indeed prettier in Halo 4, I don't think they look as good because the environments are possibly bland. Your thoughts?
