Wax lasts longer and doesn't deteriorate at all. I've pulled toilets that
are 60 years old, and the wax looked practically brand new.
Only in certain applications, like wall-hung toilets, do synthetic seals
work better (I think).
I still prefer wax, it's got a "traditional" look and feel, and I think
that like a diamond, they last forever.
Apparantly Fluidmaster feels there's a big enough market for elastomeric
seals to manufacture and sell them. Here's their "no wax" bowl to flange
I notice that they don't warrant them "forever", but only for 10 years...

One of the big benifits of wax is it doesn't compress but "squeezes" to
fill the void. Rubber compresses and constantly pushes back against the
toilet. You would always need the proper size rubber to fill the void..
