I've not used any of those controllers, so it's hard for me to say. 
A 'proper' controller is probably a highly subjective topic I would think :)

My X-Box controller functions as well as any, i.e variable throttle curve, min throttle , max throttle, variable brakes, lane change for digital - mappable to any button. Multiple throttle lever options for left and right handed people. etc.
Not trying to sell any :)
