for me it kinda depends on what the other stuff is -- or what your style is in general. for lack of better words "classic" or "modern". if you're talking about workwear boots, chunky cable sweaters and vintage-y a2 bomber leathers go cuffs. sleeker slip-on boots, minimal knits or more modern looking leathers go no cuffs. still, it doesn't matter that much. I only have cuffs on a few suits. everything else is plain hem.
