I would combine it with DD-X and when you want a cheaper developer alternative: Microphen or Xtol. But last two are powder developers and they have less convenience then DD-X which is a liquid concentrate.
But also Kodak HC-110 (also a liquid concentrate) would be a pretty good choice. For the rest it's a matter of taste. Some people like e.g. HP5+ and Rodinal, some people hate it (too much grain). But of course it's also depending on the film format.
