Sorry if this isn't the right place to ask this, I couldn't find a linux-no-stupid-questions community lol.

I'm migrating again to linux, and working on Linux Mint for now to avoid a huge change due to my upcoming program for school soon where I won't have extra time to fiddle with things. So I'm trying to get everything set up, and download my most used applications, but I'm trying to figure out - should I be downloading the official software if it's available, or is it better to find a FOSS alternative instead? I plan to go with the apps that come with it like the libre office instead of Microsoft, obviously, but I was looking at Discord and there is what appears to be an official looking option in the software manager app, and below it a FOSS WebCord option. Or, if this one isn't the official, I could always go to the discord site and get it from them if they have it available.

Does it matter which option I go with? Is it better to go with official software if possible? Or is it better to go with FOSS for more control/privacy?
