Yeah, I'm not sure that Bakker, who I haven't read yet and may never get around to, is particularly like
Martin; it's just that there's an overlap between the two fanbases. Joe Abercrombie is another one a lot of ASOIAF fans seem to like. So is Steven Erikson, who the OP has tried and didn't care for. I didn't get much out of Gardens of the Moon
either. Daniel Abraham, a frequent collaborator of Martin's and the script writer for the ASOIAF comic adaptation, might also be worth a look; his Long Price Quartet is pretty sharp character-driven fantasy, though it starts a little awkwardly.
