I just want to no out of both of these 2 tablets which one has a better picture and brighter in sunny conditions an also which has less lag.

im using a Galaxy S2 tablet works perfect

I use an iPad Air 2 and it works great. Video and pictures perfect so far.

Air 2 Cellular, it's awesome...

Appel I Pad 2 with 4G ! Is Awesome cause DJI Aap is more good with Appel

I use the iPad Air 1.  I like the big screen.  But, I do have to squint a bit when the sun is high in the sky.
