Google versus Apple. Rivalries don't come much bigger than this.
Well, technically, HTC versus Apple. But either way, it's Android's tablet poster boy squaring up to Apple's flagship tablet.
With specs galore and the latest versions of iOS and Android on offer, we've got a real fight on our hands. So let's jump straight in.
The iPad Air 2 walks away victorious, and is the tablet we'd recommend if you're sitting on the fence.
Apple's build quality is far superior, with a solid, deliciously thin metal body on offer, compared to the Nexus 9's plastic build.
iOS tablets app remain on top too, with more dedicated slicker, prettier made-for-tablet apps residing on Apple's app store.
If you're an Android fan of course then there's no competition however: the Nexus 9 will be the way to go.
