If your approach to TT is to gather your data ahead of time and pass it
in, you probably aren't setting variables, or setting so few that you
are aware of them all, so use PROCESS.  If your approach is to set lots
of things in the stash via plugins and the like from inside of your
templates, you probably should use INCLUDE.

If you're setting variables all over the place, and you don't know them
well enough to be sure there are no collisions, use INCLUDE.  I don't
set variables in my templates, so I use PROCESS.
