I installed both so I know from experience that MikTex was 
harder to install.   

The problem is that its a lot of work to set up a package
building environment on Windows. There are numerous systems to 
install, TeX, UNIX tools, perl, Microsoft Help plus path problems.   

MikTex is just one
more obstacle.  MikTex seems like its a slicker distribution
package so its too bad its more work to set up.  The main
problems with fptex are not configuration but that (1) the
package is so large that it takes a long time to download and
(2) its missing crucial elements, viz. texi2dvi.

I assume the shQuote change obviates the need for my kludge to
texi2dvi.   If it were not written in perl I would have looked
at the script part too but relearning perl provides too high 
an obstacle timewise.  It seems that the direction is to move
the scripts to R anyways so I assume perl will ultimately be 
eliminated from the R distribution simplifying this sort of 
maintenance.
