I use Panasonic Pro tapes in my Panasonic. Everyone I work with uses the same tapes. I will only use those tapes in my camcorder. It's enough for me to know that there was and could still be a problem switching brands of tape, and the damage could require sending the camera in for a $head cleaning$. Considering there is virtually no difference in the price of the tapes, I am not willing to risk messing up a shoot, or damaging my camera.
I agree that the newer cameras and media are probably less likely to have this problem. However, I prefer to take risks where the potential benefits outweigh the potential losses. My advice would be to pick a quality tape and stick with it.
