Trinity War wins by default, mostly because Marvel has dumbed down the impact of its events with overuse. Even though I expect Trinity War to be pretty generic stuff, I have more faith that it'll be somewhat meaningful, because you can see that the seeds were planted at the very inception of the New 52 with all the Pandora appearances.
I kinda have an idea what infinity is about but can someone tell me what trinity is about?
From the Comic Vine page:
The upcoming DC Comics event where war breaks out between the Justice League, Justice League of America and the Justice League Dark, due to Pandora and the secrets of the Trinity of Sin.
