Glad that you included my Redmi Note 10 Pro in the conclusion, finally, but not elsewhere in your comparisons. These Redmi products are extremely unusual with their three external card holders. Surprised that this matters nothing to you.
The other surprise is that you expect Pro camera software in OEM hardware. Users wanting expert apps value the code from application experts. Generally OEM hardware manufacturers are not good at software. OEM upgrades are much less than application software upgrades. OEM applications are usually version 1.0.0.x.  Glad you noticed that Gboard (from Google) is better than OEM keyboards. Similarly Open Camera, Microsoft or Nova Launcher are better than OEM creations.
On dust & water resistance. Official certification is an additional process not officially given to my Redmi Note 10 Pro. If you dare examine the insides, or look at the supplied external case, you will Note the same physical protection, but the formal official certification was not concluded, in these earlier products.
