I think you're best off using what you're familiar with, and keeping multiple backup copies of the important stuff. I've used Btrfs for 9-10 years and haven't ever had unplanned data loss. Planned, due to testing, including intentional sabotage, for bug reporting, yes. And in the vast majority of those cases, I could still get data off by mounting read-only. I use it for sysroot on all of my Linux computers, even the RPi, and for primary network storage and three backup copies. A fourth copy is ZFS.
If you've had a negative experience, it can leave a bad taste in the mouth. People do this with food too, "I once got violently sick off chicken soup, I'll never eat it again." I wouldn't be surprised if there's an xkcd to the effect of how filesystem data loss is like food poisoning.
There is a gotcha with Btrfs raid10, it's does not really scale like a strict raid 1+0. In that traditional case, you specify drive pairs to be mirrors, sometimes with drives on different controllers so if a whole controller dies, you still have all the other mirrors on other controller and the array lives on. You just can't lose two of any mirrored pair. Btrfs raid10 is not a raid at the block level, it's done at the block group level. The only guarantee you have with any size Btrfs raid10 is the loss of one drive.
