Without a doubt pressure bleeding with the pedal is the best method. Myself, whenever I've had a brake system open, for caliper or hose replacement or whatever, I gravity bleed followed by pressure bleeding with the pedal.
Gravity bleeding is a good way to get fresh fluid out to the bleeders, and can be done while you're working elsewhere on the brakes, but you have to stay on top of things and not let the master cylinder go dry. Then follow that with pressure bleeding, with the pedal, to force the air out. Gravity bleeding won't force all the air out of a system.
Over the years I've seen various "machines" come along, every decade there's some new "tool" that's going to be the answer to brake bleeding, and invariably there is always a job that has to bled by pedal to finish a job correctly. The Mity-Vac tool can work well, and it's probably the best one-man method, but again there is always a job that still needs to be pedal bled, so I don't play around with things like that and just go straight to pedal bleeding. It's so simple and gets the job done the first time, every time.
Pedal bleeding is how I fix soft pedals that are the result of other methods and is the best way to get a rock hard pedal, and who doesn't want that ?
