This user prefers Hanyu Pinyin because changing -eng to -ong is weird when the Zhuyin Fuhao hasn't been changed from ㄥ to ㄨㄥ; plus Pinyin is not English, it's a system just like Zhuyin Fuhao, just because it is written in Roman characters, doesn't mean it needs to be pronounce that way, like the Q, Zh, C.
原體
This user prefers Traditional character because it retains a lot of Chinese scripts that were used for a long time. (Although some of the current simplified versions were really the original scripts.)
