Who wins these one-on-one fights and how/why?

I don't think Illumi can control smoke puppets

He absolutely can't. Not only they are not human, they are already being manipulated.

I feel like in most cases Morel wins he's seemingly more inteligent and clever his stamina is no joke and his aura is impressive.

I'm not sure we can conclude that he's smarter than Illumi; while it is true that Illumi has not needed to make complex plans yet, sinc ehe was the one to teach Killua I'd assume he's roughly as smart (if not more). For the same reason, i think his stamina shoudl be comparable, and Killua ran around a country disabling controlled people for days and still had energy to fight Leol's troops. Also, Morel has immense aura reserves, but Illumi's output seems to be no joke either, at least if bloodlust scales with output.
