Playing devil's advocate, the anarchy is a major reason for me choosing Linux. Yes, the choice and "disorganization" of the whole thing can be overwhelming and inconvenient, but once you set up things just the way you want, it hits a sweet spot from me that no other OS can, (I've tried them all).
Granted, I mostly work on server-side and CLI software, but both Qt and GTK were reasonably pleasant for the odd job I needed them to do here and there.
I am on Arch, but I've found that targeting the latest Ubuntu LTS gives you a popular enough denominator of libraries that it isn't too hard to make it work on other distros, (the Arch community will usually even do a good job for you via the AUR).
