You're comparing four different things here.
House brands are products exclusive to a distributor.
Seconds are cigars that for some reason or another, didn't make the cut. For the most part, the issue is a blemish on the wrapper but not always and not absolutely.
Knock-offs are made to be very similar to another cigar. Depending upon your sensitivity to one of the components, they may taste different to you....or they could be a lousy knock-off of the original.
Overruns are cigars that were made for a distributor's order but weren't needed to fulfill said order. There are always more cigars made because of the possibility of bad cigars - blemishes, failing a draw test, etc. They are typically first quality but since the order was complete, they aren't banded or boxed to save the expense.
