I resisted it, just because of having some X configuration, knowing some absolute basics about it, etc.

But I decided to take the plunge in setting up a new laptop, and I wish I'd done it sooner. It's a lot nicer to configure (and especially to test changes in configuration in) sway than X. I don't know what I was worried about really, I should at least have looked into it - the whole thing has been easier so far than any single change I made to my old configuration (keybindings, modmap, etc.).
