I'll vote BFG AT"s and say IMO you should
avoid the Nitto's.
Had the TG's on a previous truck of mine. I got them on a set of 5 wheels that I bought and was stoked to have new tires. Still had the nubbins and all. Well, not so much. They were Ok on the street, but they hydroplaned badly here in Portland. Yeah we have alot of idiots who drive around all winter with studs and yeah we get more rain than the tropics but they HP'd BADLY. While I thought that the moire open tread blocks would ched mud faster... not really, it they caked after about 5 wheel rotations and stayed that way untill I hit a stream crossing. 2 of us on Nitto's same story. 7 other guy's in a mix of Toy P/U's, Jeep XJ's and Cj's 4 of whom were running BFG AT's. The BFG's gripped better when it got rocky adn it seemed that they could saw the wheel and get far better traction than I could meaning that the tread edge and sidewall have more traction as well. They were kind of screwed as well when it came to the mud, but they shed better and you could see a decernable tread pattern well before you could on our Nitto's. Swaped trucks with one of the guy's in a Toyota with BFG At's anfd I felt like it was a far sure-er footed truck. This is just my opinion but that's how it felt to me. Were the BFG's super in the mud... No, were marginaly better than the Nitto's well that's hard to tell, none of us got stuck so... But then I had to get kind of creative adn the other BFG guy's just kept on going.
I ended up selling the rims again for a few dollars more than I paid

and went with a set of Schwab's TXR's. I really liked these tires and am sad to see them not offered anymore. However in a search for some 33x9.50's I found the Dean SXT and met a few guy's rtunning them. All had good things to say so I may go with these but I've never met anyone who's actualy driven with the BFG AT's for a long period of time complain. It's a gfod tire that's proven. I hate to say it, but alot of people think it's just too spendy and get cheeper tires and then say they're over rated... kind of an odd statement to me when there's SO much testimonial to the contrary.
I also have 2 seperate friends and users of the Nitto mud Grappler's and both of them had multiple tires relaced under waranty for defects and excessive wear. Personaly I hate looking through 4x4 mags and seeing the "team XTREME" crap Nitto puts out adn I haven't liked their tires much so I choose not to buy them. had them on my VW's for a short while and I didn't care for their street tires either. i guess you could say I'm not a fan.
Another really interesting Tire to me is the Maxxis Bighorn. Available in 255... And not quite a full on MT, but very very agressivly treaded.
Since you're in Florida in the mud and sand, you'll want ( and it hurts me to say it

) wider tires to float more instead of sink and spin.
Let us know what you get. Either way, as long as you/'re happy that's really all that matters I guess.
Cheers

Edit: EODTaco beat me to the Maxxis's eh HAHAHAHAHAHA I feel like I should give these a try too. Nullifier here on teh boards has an Awesome taco that he's got on some 255/85 Bighorns and he's down in Florida as well. As far as I know he's REAL happy with them. hell he's got a fish depthfinder to figure out how deep some of the holes he puts his truck into are. If that's not a good opinbion to seek i don't know who's is. I live in teh NW so franlly our wheeling couldn't be any different except for the wet part that is
