Reliability/durability of Mitsubishi vs. Fujitsu mini-split heat pumps?

I am looking into a 3-zone cold-climate heat pump for my zone 6A home in Vermont. The proposals I’ve received are for (a) Mitsubishi MXZ-3C30NAHZ and (b) Fujitsu AOU24RLXFZH.

One high-ranked Google search result is of a blogger on energy topics who complains about his poor experience with Fujitsu when his interior heat pump unit kicked the bucket mere days after the 2-year warranty expired. A few other random internet comments suggest that Fujitsu may be a little more of a hassle to work with than Mitsubishi if a warranty issue arises. All told, I have not found any genuinely useful information to suggest that either brand is more trustworthy.

Does anyone in this GBA community have experience, ideally with both brands, that lasts more than three years and has an opinion on relative reliability/durability?

    previous house 1 unit mitsubishi, 3 or 4 years from new, no problems AFAIK still working 8+ years on

    Lost 7k plus using mini splits. I believe it all comes down to the installer. A good installer will back up their product. Get a bad installer and you are screwed. Manufactured warranties are based on the installer and their say, not on how the manufactures product actually works.
