We had our pepperoni greased hands all over the MOGA Ace Power, but they're not the only game in town. Logitech is similarly throwing their hat into the iOS 7 controller ring with the Powershell. A lot of the complaints I had with the MOGA are likely going to apply to the Powershell as well, as it monopolizes the Lightning port, software support hasn't improved in the last 24 hours, and it shares the same $99 price point.
Curiously, the analog sticks are absent on the Powershell, so while the non-slider design of Logitech's controller might feel a little more solid than the MOGA Ace Power, it seems like there is compromises everywhere regardless of which controller you go for. The Powershell looks really wide, even wider than the MOGA, which itself was sort of impressive in use. The Powershell has a battery with a switch, all the buttons are similarly analog, and it's also got a headphone port.
