I have a Samsung Galaxy S3, which I've owned for almost a year and a half now. It's alright, does what it needs to. Mine's taken a TON of abuse and it still keeps on ticking. I have mine rooted and running CyanogenMod 13, which is basically Android Marshmallow with some tweaks.
Honestly, I wish it had a bigger battery, a smaller screen, and a faster CPU. The battery doesn't last nearly as long as I'd like, the screen is too big to use effectively with only one hand, and the CPU, well, it's an older phone and it's definitely not as fast as it was at one time.
