Actually...those two sites are probably pretty far down the list. Christ of the Abyss the viz tends to be lowish-I guess from all the divers. I also find the reef a bit beat up and the sealife more limited than other local reefs, although I did get to spend time with a turtle a few weeks ago.
Jules' is actually in a canal-really murky water and not much to see. There are some amazing reefs-Molasses, Hammerhead, Davis (which now has a deep ball), Back Side of the Moon, etc. My favorite right now is Conch Wall. Alligator Light is also great but a little out of the way.
