Definitely the best version of Isaac that there is.

The "difficulty" of repentance simply makes the game much more enjoyable in terms of replayability, and honestly I think that if you play the game for a while, you'll get used to it.

The addition of a tainted character version of EVERY character is possibly one of the best things added into Isaac, as all of the new characters are unique to the point where the majority of them feel nothing like their non tainted counterparts, and also give much more replayability, too.
