Wonder Woman is definitely missing from the list.
Going to have to say Ben Affleck as Batman, as the darkest and craziest Batman yet. The new Spider-Man was pretty great ( a very close second) as was Wonder Woman (third). Colossus was pretty good too, a perfect straight man for Deadpool. Alfred, I thought was well done (for a small amount of screen time, although to be honest he wasn't that different than Michael Caine's Alfred, just a bit more jaded).
I think I was one of the few who kind of liked Jared Leto's Joker - he took a lot of risks with the character, and Joker as gangster-pimp is a new thing. Sure, it wasn't even close to Ledger's performance (in terms of amazing acting) but at least it wasn't just aping previous interpretations. I hope that we find out that he has capped teeth because Batman has knocked all of them out. Suicide Squad was not a good movie, IMO, but I felt that the new Joker had some promise, which will hopefully manifest itself in the upcoming Batfleck film.
To be honest, most of the other characters on that list I found pretty forgettable (particularly the X-characters).
On a related note, if we were looking at TV shows, it would be Tyler Hoechlin as Superman by a mile.
