This^Well it's not only just the lower IP rating, the no 5G, it's also lower cpu performance, older OS (still on 13), probably no updates in reality, may or may not have NFC (market dependant).
The 4G series of phones from Xiaomi are basically like the bottom of the tier they don't have anywhere near the spec of the real Note 13s
Software support for Xiaomi is questionable. Also the differences between Mediatek and Exynos are not that different and the overheating issues are fixed on the Samsungs(if you believe them).
In 2023, Samsung said that most of their phones will have 5 years support and Xiaomi said something similar so they are about equal there although this may only apply to Xiaomis flagships...
