From the purely aesthetical point of view, I have noticed it being difficult to get hold of nicely designed arrow-heads: Those that I like the most have curved front and back, and are longer than the TeX ones. I think this is the style of Timothy van Zandt's PStricks, as displayed in a paper "arnheim.ps" about commutative diagrams by Gabriel Valiente Feruglio, which I do not recall where I found.
