I think, that based on tread pattern and non-snowflake rubber the FS D AT's would be superior in very hot dry areas. The extra tread void that the BFG AT and GY SA have means extra heat and less economy in the summer. From what I've heard it's a great tire, especially for towing. But it stinks in mud, but so deos the BFG AT and GY SA.
The GY SA and BFG AT are snowflake rated which is a much more expensive softer rubber than normal tires. The FS D AT is significantly cheaper.
Probally another good choice as long as you have a set of mud rated tire chains handy.
I've been researching the MT versions and they have good reviews.
