We run BTRFS on our work laptops and have been for a few years now. Keep in mind that we're only 4 devs, so our sample size is small, but we haven't had any issues with it so far and it's been very pleasant to use so far!
We published our internal doc for how we install our Arch setup with fully encrypted BTRFS if anybody is curious. Happy to answer any questions too!

(We run Thinkpad X1 Extremes (+ the business P1 equivalents) as our dev boxes.)
