I prefer the one on the left, purely because as a product shot the product is bigger, and the idea behind expensive colognes is the decadence and indulgence of them, you don't portray that decadence with your bottle as it looks tiny in the amount of space it has. There are a few distracting things in the shot, is there a label on the underside of the bottle causing the blue hue? There is also something creeping in top left and the harsh white reflection of the catch-light on the bottle in the foreground, though I do like the yellow reflection across the white surface, which is very clean and sparkling.
