Only downside was that setting up a non-US keymap was a huge pain (iirc, in TC 10.x), at least in the console-only (Core) version of TC. Maybe this has improved by now.
Since TC by default loads everything to RAM, it is a truly great distro if you want to keep a pristine, uncluttered system. Mess something up, reboot, and you'll find yourself in your default configured state again, because nothing gets saved if you haven't set it up accordingly. The packages that boot are listed in a simple text file (iirc, it was onboot.lst), which makes the initial state also very comfy to modify.
A great distro, nice to see it going strong. Highly recommended to anybody who is into using old hardware.
