G2 looks like it'll be really nice for sims since the higher resolution makes things a lot clearer and I don't think the fov difference is that big. Index still looks fine in AC though.
Index tracking and controllers are better for non sim stuff, so it really depends on what you're going to spend the most time in.
I'd at least see what final reviews of the G2 look like before deciding anything since the release date is pretty close now.
