Also, there is a WORLD of difference between the articifial wrecks off Dade and Broward counties and real wrecks. Broward has the one real wreck, the Hydro Atlantic, but most everything else is so stripped down, cleaned, and sanitized for your protection. They're still fun, but it's not the same as a wild, real wreck.
They took USS Spiegel Grove, an amphibious assault ship, and took everything off. Same thing with the Vanderberg that's getting ready to go down in the the Keys some day, and the Oriskany.
The best spot for not-dived-that-much, but lotsa-lotsa wrecks is Bikini Atoll. Deep, impressive sunken fleets. Of course, you have to live there which would get old in the middle of the second week. And God forbid you get bent, although then you just twitch a little and walk funny - you become a character!
Everything's a trade-off - Florida has nice weather, literally miles of wrecks from Palm Beach to Miami-Dade, as well as Haitians, extreme humidity, and me. Europe has lots of Europeans - anywhere you go, you're not that far from France, and the Great Lakes are cold - people casually mention that they were diving in 36° water like it's a walk in the park.
Well, good luck with your choice.
