I moved to Pop!_OS entirely when I built my new system earlier this year (had already been using it on my non-gaming laptop for several years) and relegated Windows to an external SSD that has been essentially collecting dust — I think I've used it three or four times.
My experience isn't the same as everyone's, but I'm not in love with most multiplayer games, my work uses software that can be run within Wine/Bottles or a browser, and my preferred creative outlet is writing, which could also be done in a browser if I wasn't such a picky bitch (I am, but Scrivener barely needs massaging to work under Wine and can even be made to look native thanks to using Qt).
It'll be compatible with 5 Gbps devices, but if you're intentionally looking to restrict even 10 Gbps devices down to 5 Gbps for some reason, you might be able to find something in your BIOS that lets you do that, or you can get a USB 3.0 extension cable that'll limit your speeds to 5 Gbps.
