I think it'll largely depend on how bad it is per individual, but in my case, (one eye is perfectly fine the other was already so bad that corneal cross linking* wouldn't be helpful) it's pretty bad, I guess to give an idea, imagine playing VR with one eye uncovered, but the other with 2-3 copies of the image trying to fight for focus.

Life itself is fine, since the optic nerve is pretty amazing, unless I close my good eye, I don't even really notice it. But for some reason this just doesn't quite translate over into VR.

*Basically scratching a grid pattern into your cornea then flooding everything with vitamin B and UV - the idea being that it forms a strong matrix that resists the changes to cornea shape.

I liked the soundtrack much better overall (some of the packs sucked, but I just don't play them) and I like the movement and flow better than Beat Saber. I'm ok at Beat Saber but was never quite able to hit the hardest difficulty levels. I was playing the hardest difficulty levels on Synth Riders pretty quickly. I think it turns people off because the easier difficulty levels are quite boring, but it's very good on higher difficulty settings. They're both good games, it's very much just personal preference for me.
