I don't doubt that you can do almost anything on Linux if you want, but "easier to get good results with" is a super important consideration that I feel my more dedicated Linux-using friends and acquaintances sometimes undervalue. They'd be horrified at the idea of paying for Rogue Amoeba's Loopback (let alone for a Mac to run it on, of course), but the flip side is that it's a lot easier to do pretty sophisticated audio routing with something like that.
