I actually work for Bridgestone/Firestone and I have owned EVERY tire they make on my Rover.
And I sell them every day too.
If it were going to be my money I would get the Firestone Destination AT but make sure you get a LT load rated tire because the tread depth is a lot deeper (~17/32 tread depth). I had these on my 95 RRC (Big Blue 2" and LT245/75R16) when it snowed 18" in '09 and I went everywhere!
We were so impressed that my girlfriend got them for her D2 and used them all year round going to rallies and everything.
I currently have Destination MTs but they are 2 days old
i havent been off road with them yet.
you can pm me if you have any specific questions
