As far as the movies are concerned, John Wick has had a very good start and a pretty decent sequel while Jack Reacher (on screen) had an ok start and terrible sequel with a woeful choice of actor.
Jack Reacher in the books is a fun and capable badass and if they stuck to the source material it would be a tough choice but once you add tom "batshit" cruise and movies that stupidly deviate from a great series of books then it's John every time.
