I got the S line white (edit S Line is not the same as S curve) case and it wraps around the phone like you wouldn't believe. Not a single gap. Plus, it has great side grip so it doesn't slip. I also have the diztronic. It has the closest to stock feeling HTC esque matte black feel but is bulkier than the s line. The S line actually curves well around the phone and is light . I like TPU cases bc of the impact resistant material.
Tip: I did find it difficult to use the power button and volume buttons through the S line case so I cut a tiny piece of command strip the size of the button mold indentation and stuck it to the inside . Now my power buttons and volume buttons click well through the case. The diztronic indentations were better bc it fits more loosely.
I have a nillkin red case on the way that is supposed to be super light. So far the S line white (there is a clear version) gets the most use. You can see even see the notification light through the white.
