Breadboard methods are good for whipping up quick and simple circuits, but I primarily use a PCB. I can make simple ones pretty quick. For the more complex stuff I pay to have them fabricated.
On some ocassions, I've used a hybrid PCB/solderless breadboard method, usually when testing subcircuits of an overall design. I just make a PCB for the components, then put pin headers on it that allow me to insert it into a solderless breadboard.
One problem with breadboarding is the lack of control in stray reactance. For a lot of stuff, it's not an issue, but when dealing with things like high speed digital buses and RF stuff, it can be a problem.
