I got to go with Chuck Norris. I have read Jesus comics and, well, they are never all that interesting.
The best Jesus cameo I ever saw in a comic book was in an issue of the old (70's) Ghost Rider comic. Ghost Rider was being hassled by Mephisto (Marvel Comics stand in for Satan) and when things seem at it's darkest, Jesus shows up and Mephisto was forced into a hasty retreat! I have to admit, that was pretty cool. I mean, Mephisto has routinely battled and matched wits against people like the Silver Surfer and Thor! Heck, he ended Spider-Man's marriage (God, I HATE that story!) and here all it takes is Jesus showing up and telling Mephisto to beat it, and he does! Yeah, Jesus was pretty B.A. that particular day!
Other than that thou, Jesus doesn't translate well into the comics medium because when you boil it all down, he's a talker not a man of action. Believe me, "talky" comics are RARELY entertaining!
Comics usually don't address the issue of religion much. Nightcrawlers faith that helped to win the day. Firebird, of the Avengers, is another catholic hero. There was a minor storyline about her view of her teammates Thor and Hercules (living, breathing demigods). Of course, let's not forget Venom...comics first catholic supervillian!
Now, on the other hand, Chuck Norris is a man of few words and PLENTY of action! He translates well into comics form. People would rather see Chuck Norris kick a terrorists head off his shoulders than read about Jesus teaching "forgive and forget".
Fair? No. That's just the nature of the medium.
On the bright side, Jesus is featured in the best selling book of all time.
