I've been sticking to MIUIEXPERIENCE since it has the Xperia launcher included in the ROM. Most MIUI roms don't have a launcher so there is no app drawer.
Since MIUI sticks to the Apple interface, you won't have a launcher in the rom. If you choose Catalyst or Oodie Prime, which are just as well put together, you can download ZEAM launcher form the market or any other launcher if you prefer the app drawer.
Also, all MIUI roms have an app called Themes that comes with it. You use this app to download hundreds of different layouts and icons, including ICS themes.
