Linux users: after finishing distro hopping, where did you land?

I've been running Linux for a little over a year now and, after a recent conversation on Tildes, I decided that I need to wipe and re-install so that I can enable full-disk encryption.

Thus, right now I'm shopping around for a distro and trying out different live environments to find something that works for me. My question isn't necessarily for right now though (my hardware is old enough that I'm definitely going to need to use a lightweight distro, which severely limits my options). It's more for the future, in that I plan to replace this computer in a year or two with something up-to-date, which means I'll be able to run any distro under the sun! Any!

So, I'm curious to hear from people who have found their "forever distro." What do you run for your everyday use, and why? Also, what's your level of technical expertise? I am very far from a power-user at present, but I'd like to be somewhere closer to that when I replace my computer.
