I'm not real familiar with troff, so I can't give you a detailed
comparison, but there is a tables macro set that produces nice tables
fairly easily and there is  PiCTeX, which provides a picture
environment (LaTeX has its own picture environment).  Several people
report success using TransFig to translate PIC to TeX.  The big
differences are religous: TeX is (mostly) user-supported and
quasi-public-domain and works well with Gnu Emacs and the tools for it
are (mostly) user-supported and quasi-public-domain; troff is
(originally) an AT&T product and works with a lot of (mostly) AT&T
products, nroff, PIC, eqn, S, etc.  I think TeX has an edge in
handling mathematics; but troff may be better for documents that may
need to be sent to an ASCII device (nroff being the standard way to
handle man pages).  I think the main choice is how your organization
prefers to spend resources; troff is available as a commercial,
fully-supported product with a fairly high price tag; TeX is available
free, but will require some local support to install.
