I can only comment on my experiences....
Factory tanks/internal filters on:
Revo - fine (the blown engine wasn't dirt in the fuel related)
RC10GT - fine
TTR ST-1 - fine
two HPI RS4's - both fine
Now, I do make it a point to keep the top of the tank/cap clean as I can so crap won't get in the tank, but racers who are pitting with slop all over the truck during a race can't control that, so the potential for dirt in the tank is higher for them than a basher, who can refuel carefully.
