To make a decision never to use a project board again, based on one bad experience is very shortsighted, the malfunction was most likely due to poor design or layout in the first place.
If proper care in layout and decoupling is used you will get minimal problems.
I have used for many years and still use project boards to try out circuits of all types, digital and analog.
Over frequency ranges from dc thru 20MHz with no problems.
The only circuits IMO that are not suitable for project boards are very low signal levels, the mV's region, RF signals and mains voltages.
