Are Marinco and Hubbell interchangable?

I'm looking at marine type power inlet plugs. Hubbell and Marinco make similar 30A inlets with round stainless covers. Does anybody know if both of these fit the same twist-lock cable with the threaded locking ring? I already have a 30A marinco Cord.

I have a Hubble inlet fitting on my sailboat, that I use with a Marinco cord, so I guess they work ok. However, both are several years old, I don't know if there has been a recent change in design, that would affect the interconnection between them.

Ah, I was hoping a boat owner would answer. I think I will order the hubbell power inlet, since it is about 1/2 the price of the Marinco.
