I skipped the NTR ending altogether, but I really liked the other 3 endings. I'm occasionaly playing this kind of game (maybe once every couple of years), and I really don't like when it ends completely badly for the MC (Hence the skip, it's on me, not on you). However, when it ends either in bittersweet happiness (like the happy ending), or in revenge (like the, duh, revenge ending), it make the mid game slog (common to all games in this kind of NTR genre) worth it. However, even if the revenge ending was good, I prefered how Thug Hero Party did it. The random Eyeless character suddenly got a pair of eyes (a bit like the voiceless character suddenly got a voice), is ready to kick butts, and actually destroy the whole world in the process because fuck everyone, you don't deserve to live.
I would have pushed the whole revenge thing to the very end, with the whole world destroyed, and an "happy" ending (if you could call that lmao) with Möré and Noah happily screwing in their god dimension, with a job well done. It's a bit too bad that the revenge ending ends on a pseudo cliffhanger.
Edit: Also, Firestorm song is banger.
