Dark, because I love Umbreon, Sneasel, and Absol. Also because they gave Psychic another weakness besides Ghost and Bug, which they didn't have much of in Generation I anyway, and Ghost another weakness besides its own type. I like Steel types too but I prefer Dark types.
Steel, probably because I liked its designs better at the time.
That probably still holds true today, only because of what steel has produced since its introduction. Both of them might as well have been defensive types in GSC, Houndoom and Tyranitar's Crunches aside.
