PHP Tow Tunes vs Bank TransCommand

[agreber]

I have a 2001 Ford Diesel 7.3 Excursion 4WD with 2007 4R100 HD stock transmission (except for a 6L 26 row cooler, Balwin spin on tran filter,and Shaeffer's 204 Alltrans synthetic fluid). Question: I tow 8,000lb from Ohio to Florida a lot and was thinking of adding either the PHP gryphon programmer with tow tunes OR the Banks TransCommand for protecting my transmission with better gear shift to reduce clutch wear, etc.
What is the recommendation for better Transmission control/protection for towing? The Gryphon with tow tunes or the Banks TransCommand???

All thoughts on the matter much appreciated as I want to purchase and install before my next tow to Florida andback.
