Definitely Watch OS. May sound very 'fanboyish', considering I don't even have my Apple Watch yet. However, I've seen enough pictures, screenshots and video's to know which is better or not.
I find Watch OS to be more like how a smartwatch really should be. Android Wear just has not been able to convince me. I mean, it's not that bad. But it looks more like a smartphone OS which is shrinken down to look wel on watches. Watch OS is much more made for watches, in my opinion.
But again, I haven't got the Apple Watch myself. Time will tell whether Watch OS is really that good.
