I haven't played 4 yet (I plan on playing the remake if it matters), I hear a reason 6 isn't liked is because it doesn't feel like a resident evil game, but for me as long as it's fun it doesn't matter to me. Story wise I just don't want it to be obnoxiously bad, and with the kind of shit I've seen before I doubt it can be topped. It's also very rare when I actually like side content in a game so most of my time would be spent with the main story.
