So rather than continuing to conjecture, I went and educated myself.
Quite intriguing.

First of all, it seems that TM does indeed claim to implement semantic
networks, and more.  Fair enough.

It's quite clear that there is no question of TM vs. RDF whatsoever.  TM
can be easily implemented in RDF.  The question of whether to implement
XTM or a hypothetical RTM would IMO be entirely based on what other processing
you're doing.  If you use links heavily and have solid general XLink
tools, XTM probably makes sense.  Ditto if you generally use RDF.

TM also seems to be _very_ similar to work we have done in RDF for similar
purpose.  I think we probably reinvented the TM wheel in RDF.  I think I
have a quick and easy holiday project: RTM.
