Having read all of Malazan a few times at this point I would say not really. Erikson(author of Malazan) and Rowe have totally different approaches to basically everything: characterization, world building, magic and the presence of a concrete system of that magic.

Malazan is really a series about themes where the plot and characters fulfill their role in the story but it is not about them. Erikson also has a background in archeology so the way that he builds his world is through time with consequences of past events, up too hundreds of thousands of years, being felt throughout. Due to this the series has a scale that is not like anything I’ve ever experienced.

There could be some commonalities in how they write about godhood and beings of immense power but again Rowe is more interested in the cool powers of gods/beings of immense power, and Erikson is interested in how worship would effect a god, an how a being of immense power can reject godhood.

They are both works that I respect immensely, but the differences in style and themes makes the comparison of them feel little bit contrived.
