What is the best MFi game controller for PPSSPP for an iPod Touch 5?

[Vohuman]

I used a Moga Ace Power for a while and PPSSPP was one of the few apps that didn't require a controller reset every few minutes. I owned two and both had the same problem (at $10 a piece I wasn't too heartbroken). Although I haven't tried it with PPSSPP yet (poor performance on non-jailbroken iPhone 5c), I'm using the SteelSeries Nimbus without any issues.

A great site for info about MFi controllers is Afterpad (look it up on Google because the forum won't let me post a link). You can get a ton of info there about MFi controllers, and supported games/apps.
