We find ourselves at the same crossroads, and are in the process of switching to Sympa. While Mailman certainly has a larger user base and good ease-of-use, the currently-released version doesn't do multiple domains with delegated administration, which is something OPG/QueerNet needs desperately. With Mailman 2, we would need to install a new instance of Mailman for each domain we serve. (And Mailman 3 is alpha and feature-incomplete, and seems to need a lot of Python infrastructure to run.) Sympa has a dedicated and funded development team, a good internationalized web interface, a concept of multiple independent domains ("robots"), and a fair amount of customizability without being the inscrutable Swiss Army Chainsaw that Mj2 ultimately turned into.
