Many have migrated from Ultramon to DisplayFusion after getting impatient with the former's extremely slow development, including me. They still have their respective strengths and weaknesses, and DisplayFusion is a .NET program, which might scare some people away. So far I have no regret, however. DisplayFusion is indeed more actively developed and its author is more receptive to suggestions and feature requests.
