Oops.. with developers I meant people developing patches with PureData.
PureData itself is already in beta stage, if not a finished product.
It's the 'recommended' Windows installer that installs all those
sometimes pre-alpha libraries that can make your system instable.
Compared to Max/MSP you do spend more time patching your patches,
because Max/MSP contains many prefabricated objects.
BTW, what do you mean by incomplete functionnality in PD?
Lack of prefabricated objects that allow faster development. Naturally
you can make them yourself with PureData and/or C++, but that'll take
longer.
