Take my advice I have been studying this for months.
I ended up buying an ipad air 2 BUTTTTTT
Only cause I didn't have a lot of money to spend.
You should probably wait a few months, since there is rumor that an ipad PRO will be released this year.
If you want one right now, with your money I would get the surface pro 3.
Don't bother with the surface 3 (the small version of pro), because it has watered down hardware.
If you are looking for a gaming tablet, get the nVidia Shield
Pros and Cons
Microsoft Surface Pro 3
It's a computer, and a tablet, so you don't have to buy a pc later on
Very portable
Bigger screen than the other tablets
Supports Adblock
Apple Ipad Air 2
Fastest tablet when compared to android tablets (IOS tablet)
More companies add apps to ios, since it's only one brand
The resolution isn't that great for crunchyroll, since crunchyroll only goes up to 1080p
With the next ios update you can have split-screen, but only certain apps
Doesn't support adblock
Has an anti-reflective coating on the display (reduced sun/light glare)
nVidia Shield Tablet
A Power house gaming tablet
Supports 4k resolution
Comes with an hdmi port so you can hook it to a 4k tv/monitor
Uses the "Shield app" that has a ton of cool games
You can stream to twitch with it's integrated camera + features
You can stream games from your pc, and run on tablet
Tablet has NVIDIA Tegra K1 192 core Kepler GPU
Controller requires a separate purchase (recommended for gaming)
Baterry life isn't that amazing, but apparently Android 5.0 Lollipop helps it a bit, plus when you game you can just have it plugged in
