I don't know. I use the Linux and Windows clients, and to me they feel the same. They're not great, but I wouldn't say one is worse.

In fact, I'd say all of the modern chat apps are pretty much equally terrible. They're all proprietary, bloated, web apps with terrible clients that people only use because they have to for work. Chat apps peaked in the early 2000s when the protocols were more open and you could use 3rd party apps like Trillian and Pidgin instead of the official clients.
