mostly geany with bud/build so i don't need any project files but can easily tackle small and medium sized projects. i love the way how bud tracks down all imports, (can) clean up after compilation, and handles different sets of options in option groups - and geany does the rest
one of my projects might grow big enough to benefit from a full-fledged IDE, probably MonoD as this project is multi-platform. otherwise VisualD as VS is more stable than monodevelop. i played with both but in general, i find those big IDEs to awkward to deal with for small projects. /det
