I've never seen this debate....well not among people that actually have them. If you put the holes up...they immediately plug and you have a stuck sparge. I have 32 holes drilled with a 1/8 drill bit.
I'm not saying it's any better or worse than anything else...but it's what I've got and it works pretty well.
