That's really what I like about it - the ease of use. That's worth a bundle to me, and if I were buying a tune myself I probably would go with the Cobb. My car came with it when I bought it used recently, so that decision was already made for me anyway.
Just the ability to data log and check codes so easily is worth something to me. The only thing I do wish it had that the other piggybacks give you is the ability to switch maps on the fly. Still, it's easy enough that I don't mind doing it with the Cobb.
