My Matriarch is also my second unit, the first one broke. Some uC decided it was not working anymore and the delay and some of the other buttons would randomly switch state. It did that after I had had it for three months while I was playing live for a small group of people, it was the first time it was on for more than an hour or so but besides that nothing had happened to it. I didn't even moved it and I'm religious with dust covers and all that.
Also, the Moog One seems to be plagued with problems, which is sad given it's humongous price
Unless you just use it as something like a poly memorymoog, it's rough. I can see how a really virtuoso synth player with the right programming can probably play the score for Blade Runner on it or something without any other instrument, but the programming is a PITA. I think it's kind of like a engineer-designed instrument. For the semi-modulars you can tell they had input from really good players for most of the features and ergonomics, but the One is just "let's do everything we can on a single instrument" and it just doesn't fit.
It also really does everything. There's a guy on Reddit that has like just a One and a laptop and that's his studio in a tiny apartment. If you are working in the box but want to record analog sounds and have an ADC that will do the Moog low end justice, I guess it's great. I can't justify that money on something that doesn't give me utter joy when I'm playing it like the Prophet 10 does, the One feels more like I'm playing with an Elektron box, which I do enjoy but when I want to play synth I want to play synth.
Edit: obligatory Jump. It can even sound like an Obie https://m.youtube.com/watch?v=2-1u1qJQMOs
