What CMS do you use?
 

I am looking for some feedback on CMS's that people are using. We currently use Gallery2 to manage and feed our images and videos to our members. I have no major issues with Gallery2 as it is a great system. Just looking to possibly make a change before we get in any deeper and curious as to what options we might have.

I use mine... doesn't really work for picture galleries right now but for the tube type sites its about the only one I've seen cache support. (I say about because I found one that was like $600)
