If I had to choose between those two cases, I would choose the SolidSuit. Although I don’t have the case, my coworker does, and I can’t get over how amazing the buttons feel. However, that might not be as important to you as it is for me. Although the back of the phone feels great, I should warn you that what others have said on here about the sides being slippery are very true (there’s a reason some call it the SlipperySuit). Three reasons I wouldn’t buy it are as follows:
1. I actually prefer cases with no lip protection, and this case’s lip is too much for me.
2. The case is really hard to remove, and I like changing cases depending on the occasion.
3. There’s a hole for a lanyard on the side of the case, and it looks like it’s another spot for dust to get trapped inside (besides the hole for the lock switch).
