need a tablet...

HI!

right now i am looking for my first tablet with the option of wifi/gps/android/high resolution screen

what is the best tablets on the market right now? about the fastest cpu and quality build

so right now i am confuse about which one will be better for me....

i saw the sheild have wifi weakness..??
galaxy tab have some weakness in gaming.. ??
and the nexus 9 is a bit expansive for a 32 gb memory....

so thanks! a lot everybody...i will wait for more answers to have a solid choice to do
