I've got a SM-P600 (Samsung Galaxy Note 10.1 2014 Edition). Ok, it's rather old but what I like is the pen which is pressure sensitive (Wacom digitizer). That's the reason i bought it (used but great condition). I like how you can use it as pointer and navigate with it through web sites, even those hoverable dropdown menues. The battery life is really good. There's a LTE Version as well.

As I've seen, theres "official" LineageOS available for it. I'm really thinking about giving it a try.
