Had all three.
Maiden was a dream theme and lasted 2 years... will pick up a pro in the future and probably bolt it for a while.
JP was gone after a few months, couldn't connect with it.
Avengers theme does absolutely zero for me... music and call outs are whatever... but holy mackerel is the layout something special. Just a joy to shoot and I've been really enjoying figuring out the rules. My vote goes to Avengers.
