I really liked FE, but everything it was for me, HoA was more. FE was brilliantly creative and gripping, but to me it was palpably an early work of a young writer and I could see the rough edges. Something about the descriptions was unfinished; too much tell, not enough show, maybe? I found the writing to improve in large, quantum leaps as the series progressed, and HoA was as good as anything Robert Jordan ever wrote. WoA was, for me, slow; I didn't find the politics that exciting and the machinations seemed stretched (there, Jordan still has something on Brandon). And I agree with Dracula; Zane was not the Kelsier he was intended to be for Vin (apropos of that: Brandon said that Zane was written to represent the Kelsier way of life for Vin, in contast with Elend; does it seem to anyone else that this dichotomy was just slightly weakened by Elend's being made Mistborn anyway, in the end? Vin sort of got to have her cake and eat it too, there). So I rate them 3, 1, 2 in order of preference, but don't get me wrong: I read them all in one obsessive sitting each, so they all worked. For others, of course, what I found marginal they might find central.
