How can you compare two different laptops? I'm comparing windows and linux on the same laptop.
I personally use debian unstable with a tiling window manager (awesomewm) without a specific DE. However, I generally setup Mint for all my colleagues on the same laptop lines, and there's one colleague running Arch. We all have very similar battery lifetimes.
