It's been a while, but GNUCash seems to be OK. It runs on Linux or Windows.
I'm not a huge fan of Linux. I've had it on several machines and probably won't do it again unless I'm just going to load it and never change it. Resolving library dependencies is more than I care to screw with and seems much easier in Windows.
Keeping everything updated with Linux can be a pain, if you're not dedicated enough to it.
