Either will be fine, I tend to prefer btrfs on laptops (and desktops with consumer storage) for the ease of managing subvolumes/snapshots, the ability to use `cp --reflink=always` to clone big shit (git repos usually) instantly at (almost) no cost and the lower background drive wear. Generally btrfs is friendlier to use but bugs and failures are messier — I haven't had btrfs blow up badly in years but I'd make a backup schedule and stick to it anyway. I have a btrbk job fire and sync my latest snapshots off my work laptop whenever I plug in my external backup drive, I'd recommend something similar if you value your data and time.
