I've had a mixed bag in this regard from Apple. I do not suffer from OCD, but I do have severe anxiety that can sort of present like OCD sometimes. Fortunately, after talking to a counselor and getting on the right anxiety medication, it is no longer an issue. So things like a not 100% perfect gap in one little spot or a little nick in a key isn't going to bother me these days. And even if it does, I will likely forget about it within a day or two.
However, I have also had issues with Apple gadgets that I think were reasonable to complain about:
1) My iPhone 4, iPad 2, and iPad 3 all had to be replaced multiple times for dead pixels and dust particles under the screen. I find both problems unacceptable. I also had many home buttons go bad on iPhone 4. Apple has fortunately fixed the screen problems in most iPad models now with laminated, higher quality displays. Many of my iPad replacements came with scratches and dings, and the iPhone 4 replacements I got seemed to get worse and worse cosmetically. I finally had to settle on one that had a good screen but a dinged up antenna band.
2) I've had two different iPad Pro models spontaneously start sucking down battery power in standby mode, to the point where I've had to either charge them every other day fully or turn wifi off to get the drain to stop. I still never figured out exactly what was going on, but ultimately chalked it up to software. One of the times Apple just swapped it out in store, even out of warranty. Another time, I had to fight with them because they tried to charge me for a whole new iPad, almost full price!
3) I've had AirPods, Apple Pencils, and other accessories go bad here and there--they never seem to have a problem just swapping those out in store.
Anyone who's scared to send their fancy MacBook in for repair though? I totally know the feeling. I've seen how the typical Genius handles gadgets behind the counter, and it is far rougher than I would treat an expensive and mission-critical device. They slide them around, flop them down on table tops, whack them into stuff, slide stuff around on top of them, etc. I'm sure it's just because they're so over it--they do this all day long and are far beyond caring about your personal device.
