AFTERPAD

Hi Everybody,
I am hoping I can ask this here (sorry if not) but here goes nothing...

I was wandering if anyone can help me, what it is, is that I am going to buy a mfi controller and wanted to know from anyone what controller would be the best one to get to use on an ipad air 2.
Where I am for ios controllers I have a choice of getting either Mad Catz C.T.R.L.i, Steelseries Stratus XL, Moga Rebel or steelseries Stratus. I've looked at some reviews and watched some videos and I can't make my mind up so I am hoping you guys can help me decided since the cost of the controller isn't a problem for me.

So please be gentle with me 😊
