Notebook Backpack

I want to buy a laptop Alienware m15x.
Backpack laptop What is the best: Alienware Odyssey backpack or backpack Logitech Kinetik?

These things are always somewhat subjective, especially the design aspect / appearance. I consider the bag Logitech for better and more functional, but the color turns me off a bit. I think the bag Alienware is a step in the quality, but easier on the eyes. Logitech has a better filling.
I have included links below so you can read detailed reviews of the two bags.
