There is no airline/equipment type in my experience that jumps out as having a disproportionate number of delays.
I've had mechanical delays on AA MD-80s... at about the same rate as I have had mechanical delays on other types and other airlines.
I would assume the age, flight hours and number of takeoff/landing cycles for any aircraft is what correlates with the amount of maintenance required, far more than which type of plane it is, among any of the current commercial aircraft being flown. If one type of aircraft was an outlier in this regard, it would soon be phased out of service and nobody would buy them.
