Personally, I avoid the C-53 wreck like the plague. Waste of time and breathing gas when there are better things to do. There have been a few times we've done it to a atisfy someone else on the boat and I found some cool critters to look at, but It was the lowlight of the trip.
Like Gordon, I would happily dive Columbia Shallows every day. Columbia Deep is also a favorite, particularly when we can start on Columbia Deep and finish on Palancar Bricks. You need bigger tanks to do that. You also need bigger tanks to do Devil's Throat. I would not do it on an 80. It's also best to know the capabilities of everyone in the group. I would not put Devil's Throat on the must-do list. All of the Palancar sites (Horseshoe, Gardens, Caves, and Bricks) are worthwhile. Chances are you will do at least two of them in a week of diving. I think Paradise is a better dive than most people give it credit for, perhaps because it is often crowded. It's a great place to see octopus at night and a great place to find all kinds of little critters during the day. Look in the algae beds there, too, I've found pipefish there.
As others have said, it's a matter of taste and what the particular day is like.
