I've heard it doesn't change nothing at all. and beside it once you update to it, you can't downgrade to previously version.
I've tried the lastest version of MIUI for cancro(MIUI10 8.9.13) for nearly one year. Before Febuary, 2019, I tried the PixelExperience(based on Android 8.1) and its new features & mini size touched me(I can use my face to unlock by Google Smart Lock. And 16GB isn't enough nowadays). But finally I missed the convenient settings and stability of MIUI, and Android 6.0 can still running most of the apps.
Of course, I have deleted some useless system apps(for me) like Mi Video\Mi Game\Mi Browser. In this case, I installed MX Player and Via(also Google Webview Core). To make the ROM better, I also changed the theme(bar, lockscreen), fonts(changed to MiLanPro by an app[because Magisk doesn't work on this ROM]), launcher(with a good icon package) and wallpaper. It doesn't slow down the phone. Just try it!
