I've also been using btrfs for 5+ years. When the USB stick I keep my home server's file system on didn't boot after a power outage I stuck it into my PC, performed the simplest repair on it (don't remember which) and everything was great again. The most annoying issue I've run into (and I really hate it) was being low on space and it being really hard to free some since it's very intransparent what's actually using it - but with btdu I mostly got that under control as well. That said when repairing the boot drive I did experience some confusion due to there being multiple different ways - the documentation could be better on that front. For simple things at least (subvolume management, snapshot creation, checking free space) I've been quite happy with the btrfs command line tool.
