In general... i think:

1) TOA - good at producing nice visual (at least presentable), good art sense, some are quite creative, but not so good at presenting ideas when come to presentation part. Good place to go if you want to be designer, illustrator, animator, art director, multimedia designer.

2) MMU - Its a University, they do have proper structures for the syllabus. So you learn more than just technical skills. Apart from learning the creative subjects, you need to learn alot of other subjects such as Law, Management, IP, philosophy... etc. You have the chance to learn alot of different things a little here and there, but it is up to your interest and what direction you want to go.
Good place to go if you want to be an Account executive, Creative Director, Management Team, Art director, Producer, of course you can also become more into technical person such as designer, illustrator, animator, art director & etc. Its a self learning place, so it depends on your own initiative. There are good & bad students produced from here. If you are good you will be good other otherwise. Last but not least, there are some below standard lectures.... so up to you.

3) TAR - They have just introduced the Multimedia course few years ago. I did see lately there are some good works from them. Many ppl went there study mainly because the fee is more reasonable. Not so good at presenting idea and come out with the entire concept / strategy.

4) LKW - Fashion show place for rich students (Just general perception, does not apply to all students), somehow when come to presentation skill at bring out their ideas / concept, i think they are not bad.
