Tamiya tape is excellent, although expensive. It is extremely thin to give nice edges without paint build-up. It cuts very cleanly. It is also surprisingly strong, so it won't rip even when cut into thin strips. It is quite flexible for masking on compound curves, and it is low lack to mot peel up underlying paint.
3-M's blue painter's tape, available at Home Depot and other hardware store, is almost as good, and a lot cheaper. Usually, I mask edges with Tamiya tape and use 3-M blue tape for filling in.
I consider both tapes to be vastly more capable than regular masking tape or scotch tape.
