I found it horrible, clients are Electron monsters (but still bo Linux version..) that they shove in your face whenever you try to use the web version.

So far I can stick with Lync/Skype for Business at my day job, which is bad too but.. slimmer, and does the job. Most of the time.

I'm positive that they run the whole damn thing in a VM and electron together :). Its the very epitome of slow.
