Don't matter what you use. A good artist (not me) depends not on tools but on inspiration and perspiration.
practice, practice, practice and when u think u got it down......... more practice
No substitute for doing it over and over until its almost automatic. Then the inspiration will come at some point.
A good 3d logo can be done in MS Paint or anything ---- koala paint anyone? LOL
Look at the great logos made on Amiga with Deluxe Paint. Not the most high end drawing program by today's standards, but in the hands of a talented artist some amazing things were created. 32 colors 64 with HB on ? yikes!
As far as PS AA ? Yep a straight line will have none but a curve will have AA does away with the jaggies. Work in 100% resolution to see what it will look like. Or work in MS Paint and be happy with no AA.
