For me I have found that it depends on the game. I have played games that I believe would have been improved or made more immersive by switching to a faceless protagonist/mc. But I have also played games where I felt a non-faceless protagonist/mc would have helped or made the game more immersive.
I would have to say that NTR, Sissification, and Censored are my least favorite tags. For me they are my least favorite because I struggle to enjoy content regarding the first two and additionally, I find that I enjoy games that are censored less overall.
