I would prefer the height for accessibility reasons. I know mine are 12 inches high and even that that height it's a bit of a pain to get snakes (or rats) out of the enclosure without them dragging half of the bedding out onto the carpet. On paper towels it's a non issue. I could see 8 inches being tough since you don't have much space to lift the snake off the bedding to take out. Just my particular bit of insight.
