Are you using a Kindle 1 or 2? I think the M-edge top folding cover is only for the K2. Not sure about the Tuf Luv but it looks like it would cover more and maybe give a bit more protection.
I use the M-edge platform jacket for my Kindle 2 and I like it a lot.

I love that I can set it up to be self standing. Easy to install and remove. The cover is stiff giving the screen protection. The edges are open on three sides, but the cover sticks out farther than the Kindle giving some protection.
I tried the M-edge light and didn't care for it - not bright enough for me (YMMV). I use a Mighty Bright XtraFlex2 light now - brighter and easier to read by for my eyes.
Hope that helps.
