I think by now I have used all possible types of mounts.
Perhaps the easiest system to achieve precision mounting
are the RBT mounts.  Easy and fast, provided that the
images are reasonably aligned to start with (which should
be if they are taken with a stereo camera).  I have not
used RBTs with glass and don't really see the need for it.

For my most valuable slides that must be better preserved
I use aluminum and glass.  I also use aluminum mounts for
tricky alignment or tricky cropping.

You could achieve precision mounting (good enough for home
projection) with cardboard mounts.  I know many people do
an excellent job using heat seal cardboard mounts.  With a
little practice you can check alignment in the viewer...
you don't need to go to projection to see how well a slide
is aligned.

The bottom line is that there are many choices and it is up
to you to try different systems and weight cost, time and
convenience.
