No difference
for BS playing. You are refering to what called "burn" card which has been executed at Philippine, Macao, N Korea, Laos etc. Let's say you play 6 decks, 5 boxes, 75% penetration. Burn one card every rounds then the penetration is no longer 75%, you play about 15 rounds, with burn cards you play 14 rounds and you see 14 less cards in the process, so penetration worsen to 70%. If you play such game, you want to play as many bixes as possible to generate better penetration.
