correct, there are other speed increasing developers. But very few as fast as microphen but I haven't used them all.

T-Max or XTol will give finer grain but you won't achieve 3200 speed with them. i.e. with most other developers you will lose shadow detail unless you expose at slower speeds which isn't what the OP asked for.
I hear time and time again people quoting ilfords ISO 1000 figure for D3200. But people just don't seem to know or understand that that figure is derived from using ID11 and not a push developer. Its called D3200 because thats what you get with microphen and not with ID11. And beating Ilford for promoting its own developers is a pointless exercise. Not only do they promote them but they develop and test films using their own materials. Infact they optimise their films and developers to work together. Kind of makes sense to use them together, especially if you want maximum speed film.
