Nvidia Shield(Full HD resolution) is supposedly one of the best. I believe it is the only one with a mini hdmi out, which I believe can be used for FPV goggles, TV, etc. It also has a very accessible screen recording feature, and no unneeded pre-installed apps. From what I understand it is a preferred tablet for the Inspire 1. Samsung Tab 4 and Nexus 7 have been mentioned a good bit, if the Shield is a bit out of your price range. I just have only seen a couple of people post on using those, but they were positive. Nexus 7 will have less bloatware of the two. There is also a 4k resolution Samsung tablet (Tab S maybe).
Nvidia Shield $299 WiFi only $399 with 4gLte (if you have a cellphone with mobile hotspot, this is really not needed)
Tab 4 and Nexus 7 run around 150$ I believe
