I do not remember tex4ht output being as bad.  On the contrary I tended
to prefer the tex4ht output to latex2html, although it really depended
on the case.  I get the same.  I tried to process your example with 
htlatex and it is better.  One advantage of tex4ht is that, with httexi,
it could handle @math with mixed texinfo and TeX.  There may be
something broken for tex4ht with plain TeX.

tex4ht used to give a result that may be less polished but also using
less images, and was, in my opinion, ok.
