1. Home Screen
As we all know, Samsung has done several UI redesigns and improvements to their whole UI/UX system, but with OneUI, they have achieved perfection. Samsung was quite experimental with their UI systems prior to the creation of OneUI. Touchwiz came first, followed by Dream UX, and finally by Samsung Experience. OneUI was their final attempt, and they nailed it. The rounded corner-y UI of OneUI truly provides the user with the simplicity they want.
On Xiaomi's end, there was just one UI and one name that was constantly updated. MIUI is the name of the user interface. MIUI started from the beginning, from 1 to 13 presently. It has substantial UI modifications, which are still ongoing; we see new UI components every year. MIUI simply continues getting better and better every day. The majority of users are pleased with MIUI as it is now: simple, smooth/fluid, and speedy.
In OneUI, animations vary depending on your device; if you have a low-end device, such as a Galaxy A11, your animations will be janky and slow; if you have a mid-range device, such as a Galaxy A52, your animations will be larger and smoother; and if you have a high-end device, such as a Galaxy Z Flip 3, your animations will be the smoothest and fastest animations you can see in any Samsung device.
MIUI animations change across Redmi and Mi smartphones. Redmi's animations might be a touch janky and erratic, but they're still better than a mid-range Samsung. The animations on Mi smartphones will be the smoothest and quickest you'll witness on any Xiaomi gadget.

2. Home Screen
The home screen of OneUI basically tells you everything you want, resulting in a more streamlined end user experience. You may long-press to enter settings and modify any option you want, and everything is comprehensive! Samsung understands how to create the most user-friendly interface.
MIUI's home screen is similar to OneUI's, except MIUI includes an iOS-styled "all applications in home screen" experience, while you can also switch on the app drawer manually if you choose. Xiaomi also understands how to provide the most basic home screen experience for the end user.
3. Recents Panel
OneUI's Recents panel is horizontally similar to iOS, but in a nice way, as you can easily switch between your apps, with a "close all apps" button in the middle, you can also hit hold on the app's icon to split-screen, and there's also a "recently used apps" bar.
MIUI's recents can be customised to your liking; there's an iOS copycat option, a Horizontal mode, and a Vertical style, which you may switch between.
MIUI's fast settings have an iOS-like feel to it, with its own control centre and alerts segregated for the greatest user experience possible, but don't worry, you can still enable the old quick settings from the settings.
OneUI, on the other hand, offers your standard fast settings menu, no separate notifications, and a control centre. With the three dots in the corner, you can rapidly change your fast settings. On the QS menu, there is also a power button.
They each have their own distinct abilities, which contributes to the sense of utilising two distinct UIs.
4. Lock screen
The lockscreen in OneUI is your normal Samsung user experience. The clock, the date, and the alerts are all in the middle. Quick applications are ready for your swipe. OneUI's lockscreen also has a unique function called "just icons for notifications," which shows only the app icons of your alerts in the centre, which is a terrific way to display your wallpaper.
MIUI's lockscreen is likewise stunning, with a large clock/date combo, a perfect location to showcase your wallpaper, notifications closed by default (can be enabled via settings), and a fantastic lockscreen UI.
5. Settings
On OneUI, all of the options have been made easier to access; they are all there, ready for you to flip the switch to the other side, so you can discover all of the different settings that Samsung has incorporated on your current device.
MIUI settings are a little more sophisticated and have a lot more options than OneUI, allowing you to customise practically anything on your UI.
6. Power Menu
In OneUI, there are mostly three prompts in your power menu:
- Power Off
- Reboot
- Emergency Mode
You need to double click these prompts to activate them (emergency mode excluded), simple and animated.
In MIUI, there are two sliders:
You slide on one of them, it works without wanting a second prompt.
CONCLUSION
There is no clear victor here; each UI has its own set of users, features, and applications. However, in terms of performance, MIUI can easily compete with OneUI; Samsung has to fine-tune their UI performance a little more, which will most likely happen with the future OneUI 4.
MIUI, on the other hand, is still ascending the ranks with its most recent release, MIUI 13. MIUI 13 boasts a lot of performance improvements, and following the success of MIUI 12.5, MIUI 13 has a lot of expectations, both in terms of speed and quality of life.
Both UIs have problems, with OneUI having an awful amount of bloat within, causing unnecessary RAM utilisation and, as a result, making your phone slower, and MIUI not having the best stability. However, because Android is updated every year, such issues are likely to be resolved over time.
