There really aren't any proper reviews of stuff like this; there may be some by people on YT that scratch surface, but there can be small issues that don't get a mention[1].
Your best bet is to ask on android tablet forums, and/or stick to the most common devices (eg. ainol).
To be honest i would say get an ainol novo7 elf2/aurora2 (tn/ips), or a used v1, or an a-n-7 fire, which is like the nexus 7 but uSD.
1. eg- i had a tablet that didn't autorotate, despite having all the right sensors, and also that made electronic noise with the headphone port (only) when nothing else was going on for a while.
