For me the best variant is Bughouse because it feels good to receive pieces from your partner and it's like Crazyhouse but improved.
What is the best Chess variant?
i agree with cris. bughouse has team cooperation which can amke it a life skill sort of. and yes jankins is correct. its is very annoying to lose in a winning position because of a partner getting checkmated. however you can tell them to stall.
I was wondering which chess variant is the most loved by the community so that I can try it myself
