My preferred method of using two-way light switches, where two switches share a circuit to control the same light, is to pretend one doesn't exist. Generally that means only using whichever switch is closest to the main entrance, because that's the one which you're most likely to need to muscle memory when entering a dark room or turning off the lights to leave.
Why?
It ruins muscle memory for the direction of the switch to be unrelated with the state of the lights. I want to switch the light in one motion without looking and get on with my day, not fumble to figure out which direction is the opposite of the current position.
There could be a case where it's more convenient to get used to switching the position, and I've certainly made bigger muscle memory adjustments1 before, but so far I haven't been in rooms where that's easier than using the same switch every time.

Nightly Notes
I generally hate things which are normally one-way but occasionally two-way. Consistency in design is everything.
Jack-and-Jill bathrooms are my nightmare fuel.

Rewiring, one might say. I haven't forgotten about that end of year post. ↩
