Real, hands downnnnn. I mean I take care of my feet and paint my toes on occasion, but I do minimal care involving my hands and it doesn't take too much to have them looking up to my standards. I just keep them clipped semi-short, cuticles pushed back, and sometimes a clear coat of polish just to look nice.
As for fake/acrylic/gel nails, nah. I think it's a huge waste of money to go get that s.hit put on, plus upkeep. After a while it ruins your real nails underneath, and I just don't think they look good on most girls. And I feel like they're a pain in the ass to do anything with, I'd feel kind of handicapped by them because I wouldn't be able to use my hands/fingers/nails in ways I normally can. I figure keeping my hands nice at home by myself works just fine for me. The very occasional random manicure where they do all that for you might be cool, but I doubt I'd want to pay for one, and I definitely wouldn't want to pay to have acrylics put on. I don't think I'd want any even if it was totally free and offered to me. They just wouldn't look or feel right on me, I would feel less myself. =P
real ones definitely. I had a uncomfortable result wrestling with a girl I once dated and she had fake extended nails and by the time we were done I had many scratches from them on the back of my neck because she tried to put me in a headlock many times. lol
