I've already voiced my opinions on a thread on the Steam Beta forums (will share links on the bottom of the post, if you want to see what I think along with give official feedback), but I'd like to hear yours.
If you don't have it but are looking to maybe try it out now, that may be a good idea if you want to start getting used to the big changes to Steam chat being made now, though I don't particularly recommend it otherwise.
