I've used DBeaver at work on Linux to connect to Microsoft SQL servers and also to some PostgreSQL servers.

It's not perfect but it's not bad. My experience was annoying (at best) to get drivers to work; particular the tsql ones (since Microsoft didn't provide Linux drivers at the time -- I don't know if that's been rectified). Once they're working though, everything else is fairly intuitive.

It's been a couple years since I moved to a different team and no longer need to connect to databases (and can't anymore... yay security). But I've considered using DBeaver at home for personal use.
