I have to go with the UH-1; as I understand it the Cobra is a derivative of the Huey. I was fortunate enough to fly the TH-1L as an SNA and the UH-1E in the FMF. The E model was underpowered, especially for Southeast Asia but the H model seemed to do quite well for the Army. I got to fly the D,B and H model in the National Guard along with the OH-6A and CH-47A; all fine aircraft.(I only had a flight or two in the B model so I'm far from experienced on that one.)
If there is or was a crappier helicopter than the Enstrom F-28 I would be surprised.
