update to marshmallow or stay on lollipop?

I have a factory unlocked g3 d855(32 gb).I wanted to update to marshmallow, so I've done some searching, and people reported a lot of bugs. They also mentioned bug fixes to some of the problems, but it doesnt feel worth it. Can anyone who has experienced the official marshmallow update please advise? Is it worth the update?
Thanks in advance
