It has a lot of options and in my opinion a lot better than the standard Android keyboard that ships with MIUI. There are lots of options to get it to look and feel (more or less?) exactly as you want it to. If you haven't already tried it, you should - at least while waiting for MIUI to release their new keyboard.
Oh, unfortunately HTC_IME doesn't have the nice looking "glow" as in the MIUI pictures of their new keyboard, but it's still a great alternative. The developer also has a "kitchen" where you can create your own skin for the keyboard, which can be found here: http://www.gimpsta.com/themer/
