If one was to include all the variations that spawned from the original Avid/Kitfox design, I'm fairly certain it is the most popular experimental kitplane in the world. Where I live there are significantly more Kitfox type aircraft around than there are RV's. And there definitely seems to be more interest than ever in Kitfoxes, Highlanders, etc than anything else I hear about.

I like the Vans RV airplanes a lot. But the Kitfox offers much more versatility along with much lower operating costs. So I believe as time goes on the Kitfox will only become more popular.
