I have to make that type of decision all the time.  In a production 
environment, PALS are expensive to program and install (they require
sockets) and you need a bureaucracy to keep track of the "firmware" level.

The forces on me, then, are to avoid using PALS.  One nice feature, however,
is that if I screw up (really! It has been known to happen even to me!) it
is often easy to burn a new PAL with a few changes, and the boss doesn't
even have to know anything went wrong.

For home use, if I had a PAL Burner, I would probably use PALS whenever I
could to reduce layout/wire-wrap work.  Since I don't have a home PAL-burner
I tend to use standard logic (but since I don't really do much home stuff
anymore, I guess I can't really say I use ANYTHING.)
