hey, i've got a marshall 1965a, and yes, there was a b version too. It came with the 3203 artist head which i also have, or the lead 100 mosfet, which i had and sold. they are real cheap on ebay. i picked mine up along with the mosfet for $400, sold the head for $300, so a damn good deal. Sorry i don't really have much to compare it to. Its the only cab i've ever had. I played my friends 4x12 (peavey ultra cab?) once and i didn't really notice a difference in the bottom end. i actually like my 4x10 better. plus... ridiculously light. probably weighs the same as the head.
