If you're into the main two comic companies you've seen your share of event comics. Tie ins, one shots, etc. But when was the last time you actually liked the main book it's self? A couple of Snyder Batman crossovers had me preferring the tie ins (I haven't gone through Year Zero yet.) Does Justice League Generations Lost count or is it just considered a spin off of Brightest Day? Maybe 52? At the moment I can't think of anything else that works.
I like the idea of events but they haven't really been delivering. Some of them I didn't follow because I didn't care (Trinity War) others have just been boring.
