I have two pairs of Nike shoes, they're awesome. The best I can get. I had one Adidas too, that was also cool.
Nowadays, I think Adidas is becoming a bit overpriced. And I bought a kinda expensive T-shirt of Adidas but it became disgusting after first washing. I mean, its quality sucks. By looks, Adidas has better apparels but they don't last long and their print tear off. Nike doesn't have that elegant apparels (as compared to Adidas, overall they look good too) but their quality is marvellous. They don't get damaged.
In case of shoes, comfort is equal but the looks, price and durability is better in Nike.
