Which PRIZE do you like the most? (SIMPLE)

Okay, I'm about to run a contest, so I just want to know what prize people would prefer.

So which do you like of the following:
-iPad Air 2
-GoPro Camera (Hero4)
-iPhone 6
-Canon Camera (like any on this page: http://bit.ly/1u1xoZt)

Which do you like best (and can you list them in order)? And if you don't mind, can you mention which country you're from. Most of my visitors are American, so I want something they'd prefer! Also, I'm in the photography niche, hence the cameras!

Thanks!

USA and I would prefer the iPad Air 2 since I already have the iPhone 6 (if I didnt, would prefer the iPhone 6) So I guess those I would rank 1A and 1B

Just make sure It's not hosted here as It's not allowed, cheers.

tough i would prefer a go pro. But iphone as prize is evergreen

Would make more sense going with one of the cameras

Thanks very much, guys! I know what to do now.
