For me it is not about looks because I think Mathematica typesetting/
rendering is miles ahead of competitor products. It is about ease of
use. There is Symbolize in the Notations package which can get you
closer to something that works better but the best analogy i can think
of of how the other product works is if instead of Subscript you had a
function SubscriptVariable in which the subscript was a different
context e.g. SubscriptVariable[Global`x, NewContext`i] rendered as x
subscript i.
