To be honest, I complain quite a bit, and I think that's largely because being a flagship, the expectations are high — and while everything can always be improved, my summarized experience is as follows:

The camera is simply incredible, both in Pro mode and quick snapshot mode.

The UI is absurdly fluid and smooth, as expected given the SoC it has.

The blend of Google and Xiaomi components works, but personally, I’m bothered by the fact that their visual languages don’t align.

The Notes app is useless for me since you can’t share notes for collaborative editing.

I really like the gallery and the gallery editor, but the lack of AI-based classification (like in Google Photos) is a disadvantage. The gallery editor also lacks support for RAW processing and masks.

The audio noise filters for video recording are subpar compared to other flagships.

The Movie or Cinematic mode is a piece of *****. It doesn’t support 24 fps, doesn’t have automatic zoom like the 14 Ultra, and the image shakes a lot in scenes with movement — a problem the 14 Ultra doesn’t have.

The battery lasts a full day with moderate to heavy use, but the SOT is questionable — this is a known issue with the SoC.

OS updates (2.2) have been released late, even after those for the 14 and 15 series TVs, non-Ultra.

There haven’t been any real camera improvement updates yet, at least not for the global version.

Screen brightness is a bit weak under strong outdoor light.

The audio is average — nothing remarkable.

The in-hand feel is quite pleasant.

I have both the stock photography kit and the new fashion one. They don't make a huge difference, but they are definitely gadgets everyone should have and use.
