It's an interesting question and I've wondered the same thing. winRAR is a piece of nagware that works great but has a reputation of people not ever buying it. I've seen phrases like "what?! you've actually bought winRAR" many times online. On the other hand, Sublime Text seems to have the opposite with lots of people proudly exclaiming they've purchased it. Without knowing actual numbers it's impossible to tell but there is some culture at play here.
The type of software probably plays a role as well. Sublime text is heavily used throughout the day but I can go weeks without needing winRAR.
