It would be interesting to see how much of the EXE file is actually
code.  Possibly you're seeing the result of TLINK putting "far"
uninitialized data in the EXE file, instead of letting the loader zero
the data (the MSC approach).  Once the programs are loaded, the
difference may not be nearly as large as the EXE file sizes would
indicate.  Admittedly, it would be nice to not waste the extra
disk space.
