I'd be wary of getting anything with really old Android as apps simply stop supporting older versions.
I'm not a fan of Samsung or Sony, as they overly customise Android making for late updates and early withdrawal of support.
Samsung tend to be good quality hardware, IME.
+1 for the Nexus 7 (2013), updated to Android 6.
Anything you can get with an OLED display will be amazing in daylight, but the price will make you choke...
