YSE is expensive of course the quality is better. But for me, is better to have a latch inside because if once the lock is broken the door will just open. If you got additional latch with pack lock inside at least there is another 2nd layer of protection. So far all the the lock set control all the internal latch. No point if your door have multiple latches but once the main lock is broken or open. All the latches will be open.
