I guess I will tell my opinion here and it's not 
aimed to be the final statement for "Pd vs Jmax".
I've got both installed and i'm rather using PD
which scarcely provokes clicks or latencies,
sorry for jmax...it does.
This is essentially due to the fact 
that jmax uses a Java's GUI 
which is way slower from the PD's GUI 
using TCL/TK.
Of course, many paremeters have to be tuned
to make PD and jmax work the best way on your system
( frags for PD,..... ) but, once this is done,
PD is proved to support much more complex patches
running together.

Concerning ALSA, the sound is generally speaking
of a better quality and it supports full-duplex.

cheers,

PS : anyway, you don't have to choose between PD and jmax,
both can be used at the same time on a good machine.
