I'm four months in and love my X-T5, no problems at all. For me it came down to format choice, APSC. The brand choice became Sony or Fuji as Canon lens selection seems lacking. Then read up strengths and weaknesses of the two. But physically looking at the camera made the difference. I have XL hands and the Sony actually felt too small to hold. I preferred Fuji handling but the big difference was the dials. I could see how to adjust ISO, aperture, and shutter speed without instruction. Took me back to days of shooting film. I just wanted to use it. I don't like wading through menus and I don't have to with this camera. It has a ton of features I haven't used but I appreciate that I can go out and have fun, taking great stills, and learning the advanced stuff at a very slow pace. I've only shot a couple videos and have no idea what to do with the histogram. I'm not sure I care, love the camera. As for 4 vs. 5, that's hard to say. I don't want to video of myself so I prefer the tilt screen on the 5. The resolution increase isn't a bad thing, I trim my shots quite of bit and more res helps with that. I kinda wanted the latest and hopefully greatest. But if the dollar savings is enough to help out your lens budget then go for it.
Here is a short segment explaining some good and bad things about each of the shutter types Fujifilm uses.
Your X-T10 does not have all of the different types, but give each of those it does have a try and see if you like them. Enjoy your new camera!
Like others have stated, it happens and can happen to any brand make or model. All industries are subject.
I have had my X-T5 for 2 months and it is perfect. I come from Canon FF both EF and RF and Nikon for analog, all companies and segments with incredibly high QC rates. This Fuji is the same, from mechanical to software, top marks.
If you look for negative reviews, you will find them. Complainers are 10x more likely to voice an opinion than those satisfied.
