It would be helpful to understand your electronics, room and listening habits before giving an emphatic recommendation for any of the products.

I have not been a fan of the half dozen B&W speakers I've heard. I also have no idea how you like their sound. I liked the Golden Ear Triton 2 I heard, and the Triton 3 should be similar with one less woofer and mid-range driver, but we don't know if you will be using additional subwoofer (as is popular these days) with any of the speakers you mentioned. I have not heard any Marten Logan box speakers.

Sort of echoing shp, any opinion I have would be worth more (and likely change) if I knew what the situation is. Just shooting blind, I like the Motion 40 on paper, but the Triton 3 might offer deeper bass if not using a subwoofer, so it already depends on how YOU prioritize bass extension.

Can you demo any of your choices with your own gear? It's crazy how much difference partnering equipment makes to loudspeaker sound, at least as much as the listening room itself. Another consideration is the kind of music you prefer, if you love rock in your car with a couple 12" woofers helping out the golden ear would probably fit, I find martin logan panels make my ears bleed but many people love em. B&W's back in the day, like kef had a 'british sound' to them and took loads of power to come alive I don't know if thats still the case. Unless your going to rebuild your whole system, demo at home.
