[erlang-questions] pg2 vs gproc?

For term() to pid() mapping I've always used gproc. For the same thing
my coworker always used pg2.

I am making a comparison now. There are some features in gproc which are
not in pg2:

* Await for registration
* Per-process properties
* Aggregate counters

Whereas pg2 "natively" supports mapping one key to several processes
(which can be easily achieved with QLC in gproc).

Any more differences between them?
