I can compare to Kindle Fire original, N7, Nook HD (Hummingbird CM 10.2), Nook HD+ ((Ovation CM 10.2). The stock, rooted, 2.7 is my favorite
GPS, front/rear camera, MicroSD Card, microphone, hardware keys and IR are important features for me. With MightyText and Magicjack installed, I have what is almost a phone. A 7 inch GPS is a wonderful thing and that is difficult without the External Storage. Downside is weak screen resolution and poor laggy screen with Touchwiz (use Nova Launcher).
If screen resolution is a major factor, the CM ROM Nooks are a great value.
