How does this phone compare to the S6? (same price right now for unlocked).
I currently have a 4.3" phone, and imagine 5.7" is going to be too big for me. I'm not aware of any stores that stock them (it'd be nice to compare them - I do like how slim the bezel is on the S6). The camera in the S6 is better too, right?
You can try holding the iPhone 6S Plus as it has pretty much the same dimensions as the 6P. My previous phone was a Nexus 4 @ 4.7" so upgrading to the 6P was initially intimidating, but I've quickly gotten used to the size increase. It'll definitely be harder to use the phone one handed but you can workaround it in most cases (placing homescreen icons nearer your thumb for example).
I believe the camera is on par with the 6S, in some instances it might be even better, but you'll definitely have to do some research and judge for yourself. There are plenty of sites with photo comparisons given that they were the two android juggernauts of 2015. The stock Google camera app is rather barebones so you'll have to get a manual photo app from the Play store if you want more control.
If you want stock Android, then 6P no contest. I've never used TouchWiz but I've heard mostly bad things about its performance, which apparently degrades substantially as time goes on.
If you care about durability then the S6 wins out imo - the aluminium on the 6P is easily scuffed and the body can be bent much easier than the S6. Both use Gorilla Glass 4. If you're generally careful with your phones though (using a case, don't put into tight jean pockets, etc) then it's a non-issue. I've no issues with mine but I've read plenty of reports of slight bends and then there's
