after affects

I just want to know if anyone here edits videos using After Effects rather than Premiere. I usually do all my cuts and such on Premiere but if I wanted to do some special effects I'd do them in AE and import them to Premiere. Do you think it would be more effective to use After Effects alone...

I recently subscribed to Adobe Creative cloud. I noticed some pretty cool plugins that can be installed on After Affects while watching Youtube tutorials. My question is, what are your favorite After Affects plugins, and what do they do?
