Do you guys think there is any truth to that though? I think that would only apply to the drain plug, but I am curious what people think. Any recommendations on better oil filters, than OEM, to trap more particles? Thanks!

Since you would remove the metal debris from the magnet at every oil change there should not be any accumulation large enough to significantly "mound" up to the point where the magnet cannot hold it.

However, the filter would be next in the oil circuit and capture the metal in case what you say is possible.

If you did ever have a mound of metal accumulate between oil changes then its likely your engine would already be in very bad shape and immediate tear down and overhaul would likely be required to avoid a catastrophic failure.
