How is called the Chinese language in Taiwan?

I feel it is a very political issue. In my knowledge, there are the terms 華語, 國語, 普通話, even "Chinese dialect".

In this context, what is the most common word used by Taiwanese people to refer to "the Chinese language"? (For instance in a politically neutral context where they would like to say: "This foreigner speaks Chinese very well.")

In my impression, 中文 is the most "neutral" term.
