It's pretty hard to have a valid opinion on one vs the other if you don't have both - but I'll try. I have the Gecko Luxe and I like it a lot. One thing I noticed looking at the picture of the Tuff-Luv is that the leather is cut away from the buttons at the bottom. This is probably a good idea, as on mine the leather sort of makes a ridge along the bottom of the buttons, making them a little harder to use. But not so hard that I'd throw it away to buy a Tuff-Luv
I might try to trim the leather a bit, though.
