You can take this with a grain of salt, but my friends at Bandai US tell me the top 4 Heisei series in popularity within the US are in order:

Build
OOOs
Gaim
Double

Also, the Kamen Rider initiative over the past year was considered a huge success and there's a lot of cool stuff coming as a result. I'm pretty stoked for this Anniversary celebration. 50 is such a milestone for any franchise. It makes me think about all my favorite shows from the 80s and 90s that I still celebrate despite not having any form of new media and just an occasional new collector toy here and there.
