Laces because those are the shoes that are usually on sale. I like the ones with the lace tuck-in to prevent flopping laces getting wound up.
Also, I have a bone spur on my right metatarsals from an old motorcycle accident. Laces let me put less pressure on that area while still getting a snug fit. BOA looks good though but it does look plasticky (environmentally speaking) which sometimes influences my purchase decisions.
