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.
