I grew up here in the Philippines and I learned Chinese Mandarin using Zhuyin.  I had the opportunity to talk to people who uses pinyin.  I realized that there are pros and cons in these two, here it is: 

Zhuyin

Cons : Zhuyin is more difficult to learn especially if you do not have a background in Chinese, since the characters are also in the Chinese format, it will take you more time to learn it. 

Pros: Your pronunciation would be more accurate since you are reading it using Chinese characters. 

Pinyin 

Cons: Unless you have a Chinese background, there is a big percentage that your pronunciation would be wrong...unless you have someone (teacher or a tutor ) who is really good in reading the Chinese characters.

Pros: It is written using the Alphabet therefore it is easier to read.  

Do you agree? let me know your thoughts :)
