What is your favourite minecraft version?

I will always play 1.7.10 for pvp and beta 1.7.3 for nostalgia and old interesting world generation.

But new 1.18 update is very tempting now that they have made world gen interesting again and not just all flat...

I think I will play 1.18 for new survival, I already found a small server.

what do you think? What is your favourite version?
