So i need a new bag and i need you guys to rate these following bags based on aesthetics and costs.

First is a Portal 2 Bag:

An Aperture Laboratories logo and orange and white color scheme.

Second is a Firefly Bag:
Blue Sun

Third is a Halo Bag:

There are three choices to choose from.

Fourth is the Backpack of Holding:

Seems unique and nice.

Okay with all this into account the bag needs to be able to fit a 17.3" Laptop and a couple books.

So Flood which is the best?

I'd love to have that last one since my current canvas bag is ripping at the bottom.

Portal methinks.

The last one. I got my friend the Bag of Holding (smaller version) for Christmas last year last year and he loves it.

Also the first one is sold out.

Choose it, i was really torn with this and the halo backpack but decided i would prefer to keep the weight equal on both my shoulders.

Portal. Using one of those in public would make you look like a sperglord, though.

If I saw someone using that Portal one in public I would go and knock them out.
