To be honest, you're kinda comparing apples to oranges on this one.
Marker tends to focus on lightweight bindings, but they tend to have durability issues (Jesters seem to be ok, but the others have issues). While, Look tends to focus on durability, but they tend to have heavier bindings (and in my opinion...and I know people will fight me on this on...most of the PX series is crap, they're heavy and not very durable, other than the PX18 which is still not that great in my opinion).
Take a look at these two threads, they'll probably help you with your binding decision:
