mumble
- overlay that actually fucking works
- simple
- server connection (not some dumb invitation shit)
- faster
- doesn't fucking feast on resources
discord
- ease switches between channels
- wayyy better text chat
- easier to connect with your lads
- essentially just newer feature/ui wise (videos, pictures, private calls, friend system, etc.)
my take: mumble is always going to be superior for gaming, but discord is hella nice to chill with friends and easily switch between channels. a big one is that the discord overlay just sucks imo (it's always delayed and looks weird) while mumble is easy to identify the person talking. discord is definitely more like skype, tho, and i would never use skype as a video game communication service. mumble is just simpler which makes it better for video games but not much else.
