I've always found my left back pocket tremendously more convenient. It's easier to access I think and that pocket is always empty as opposed to my left front which has other stuff. Also, it allows me to comfortably carry right handed knives. I've sort of gotten frustrated lately with the lack of accessibity of some left handed options (and I couldn't possibly care less on the lock side, it's just the clip), and I've debate going back to back pocket. I would have to feel super confident in the clip though. The last knife I carried back pocket was a benchmade bone collector that was lost forever from that spot. I've had some issues front pocket too, but since I've found the knife the few times it's happened I'm less traumatized.
