Hi, I can't decide what to get, any help will be very much appreciated.

Looking for an android tablet, thinking about getting rid of my printed magazine and switch to digital. Not sure about 8.0" or larger screen, should I look for an 4:3 ratio??

choices for now:
Samsung Galaxy Tab A 9,7 po
Galaxy Tab 4 10,1 po
LG GPad 2 8.0
Samsung Galaxy Tab S 10.5"

Price Range: $150-$400
Screen: not sure 9.7" or 10"
expandable memory through SD or micro SDHC
primary uses: reading magazine
secondary uses: multimedia - video/music/internet, some skype

Thanks
