I have three laptops, two run OpenBSD, the other one Debian stable. Not sure how well battery utilization compares (don't need battery for more than an hour usually). Both work fine, and from a user-space perspective are very similar (esp. if you automate configuration and dotfiles). OpenBSD is about a magnitude less work to configure, especially if you have a non-trivial network setup (and some things, like IPv6 LLA aliases in /etc/hosts, Debian stable does not even support). If you are reliant on garbage like NetworkManager and Gnome/KDE auto-mounting the story is probably different, but that is just a good opportunity to learn better ways of working on Unix.
