the kind of man (who/that)...

[DoWell]

A choice goes like:

He is not the kind of man (who/that) goes back on his word.

which one is the proper choice?

Thank you.

Both correct, but as shown by the New York Times:

2,330 from nytimes.com for "kind of man who"
http://www.google.com/search?hl=en&q=site%3Anytimes.com+%22kind+of+man+who%22&btnG=Search

161 from nytimes.com for "kind of man that"
http://www.google.com/search?hl=en&q=site%3Anytimes.com+%22kind+of+man+that%22&btnG=Search

the 1st is very much preferred, talking about a person. The 2nd sounds to me a bit impersonal.
