No case. I had a Casemate on my last phone, but it kept getting really hot when I would play games on it. Had an Otterbox before that. Those things are bomber, but they're so bulky. The rubbery texture meant it was almost impossible to get the phone out of my pocket while sitting down (IE driving).
I'm not using a phone case currently because it interferes with my headphones but when I do I use something similar to this (just for a Galaxy S5). My aunt randomly gifted it to me and it's worth it for some of the strange/messy looks I get from people in public alone.
I have a Lifeproof case for my iPhone 6, lost the headphone bit for it but it's kept my phone safe from harm.
Never used one before. Had to when I got my Note 5. The back has zero grip to it. Ended up getting a really thin, clear, plastic one. Very happy with it.

No case, but I couldn't see myself ever comfortably holding a case on a 6inch phone. Used to on my older, smaller ones.
got a Peel for my 6 right away, but was very disappointed in it. felt cheap, especially considering the price. got a crack about a month in. just upgraded to this guy: they liked some of my photos on IG so I checked them out and their cases looked cool. will probably try to find a cool/slim skin to go under it.
