there are a few factors and each muzzle can be better for many configurations.
speed of reload- for me the open is faster but I have seen commercial guys who used the closed muzzle and could reload in like 3 seconds.
shaft type- for a small closed muzzle you must be using notched shafts for a large closed you can used a notched shaft, pinned or mini sharkfins, and an open muzzle can use all shafts
line arrangement- in a closed muzzle you have more option to route the shooting line, in an open muzzle you need to use it for securing the shaft
line shaft vs freeshaft- only line shaft for open muzzle guns
aiming picture- I like the open picture an open muzzle given but I have heard spearos say they can aim easier with a closed muzzle cos it acts like a front site.
I'm sure there are more, but it is largely preference
