I think it's going to come down to a war between TeX and eqn.  Each is more
common in some environments.  Expressive power is similar; the eqn version
of the above is (assuming I've read the TeX correctly):

sum from i=0 to p a sub i y sub {n-i} = sum from l=0 to q b sub i xi sub {n-i}

Sticking strictly to readability, and disregarding the who's-got-which-
software issue, I think eqn comes out ahead -- fewer silly backslashes and
fewer artifacts of the odd character set Knuth used.
