Dirichlet has some theoretical advantages (such as deducing how many clusters are justified and providing non-deterministic answers when ambiguity is present). It has no run-time. It probably is more delicate with respect to parameter settings.
If you have some time budget, I think you could get some substantial improvements. If you are in a hurry, then k-means will work much better.
