Advice on Tablet to buy for Kali

Hello everyone,

I'm going to be buying a new tablet within the next day or two and wanted some advice. I am debating between 3 different tablets for pen testing; Samsung Galaxy 8.0, Nexus 7(2012), and Nexus 7(2013). The other reason I liked the 3 tablets mentioned, is because their are already other similar types of builds for these models; i.e. PwnPad and Neopwn. Also, I planned on buying this adapter for packet injection/monitor mode using an OTG to USB adapter. Do any of you have the above mentioned tablets running Kali? And if so, what is your experience with it so far? Any lag, incompatibilities, etc.?

Thanks and I appreciate any feedback.
