I'll say it again... it is all conjecture unless you've built, modified, and repaired all types.
Again, "facts" are not "facts" just because one says so.
Mark has a great deal of experience with amps and indeed said it best:

Regardless, I've worked on, built, or modded/repaired em all... total PCB with pots/jacks attached to the board does not make for reliability since the physical interaction with these components is bad for any electronic connection over time... BUT, as Mark and MOST experienced builders will tell you, it doesn't matter if its PTP, Eyelet, or PCB - they will all sound identical (taking tolerance variations into consideration).
