All things being equal, lock your bike where it's in view of a security camera.

I'm skeptical that bike lock
picking is much of a thing in RL. That said, my two different types of locks use two different types of
lock cylinders, so a would-be picker needs two sets of picks and to be conversant in picking two types of locks. When and where possible I put the cylinders at an awkward, hard to access and left-handed angle.
Park the bike next to a bike that is poorly locked and preferably better than yours hence, a more attractive bike to steal.
