Although I can't comment based on evolution of specific fossil plants, I
have heard/read (but can't recall from who/where) that dominance of the
diploid, rather than haploid, may offer more evolutionary flexibility
(therefore greater success) from the standpoint of mutational variation and
natural selection.
