Smarty is a much better. I had an ez. Now a comp, than a drag comp now drag comp/smarty. Smarty runs cooler and is alot more adjustable, and code reader, tire size adjustment, high idle option is great!
Run a Smarty for a while now, towed through the mountains with it a lot with it set on level 9. Works very well, gives loads of power, EGTs tend to be a little high unless you go down a gear when towing up long and steep hills.
I've had an ez before on a auto and it was good, never owned a smarty. I've heard a lot people swear by smarty when it comes to towing. Just don't want to spend the 400+ if it's the same thing as an ez.
