It all depends on the game you're playing and how much you get into it. Even my old WMR headset could be pretty immersive.
As far as the headset goes, it's better than the CV1, and I've even heard people argue the lenses are better than the Index. FoV is going to feel narrow on any current headset, but when you really get into a game you don't think about it as much.
