I'm not so sure. My fiancee owns a Mi Two and I've used it pretty extensively. There are some parts that really copy iOS, but most parts of the MIUI don't look or feel like iOS at all. It's a great OS and has a lot of polish to it.

MIUI is probably the best Android based OS available. I switched to it from Cyanogen and after two years I still keep my old Desire since I can't bother to change to any other OS and then hassle with rooting it. My next phone might just come with MIUI out of the box.

Interestingly, this thread and my frustration with how... boring 4.3 is on my Xperia S has made me download and flash MIUI on it.

I forgot how awesome it actually is. So very well done.
