I think that the second example is the 'more correct' one. One of the functions of the preposition (of) is describing a trait for a noun, in this case, you'll need it to show that (good) is an adjective which describes the experience. On the other hand, you might hear the first example in spoken English but i do not believe it is suitable for writing.

  • I'm fairly confident that "how good an experience" is acceptable in English writing, and from what I remember, the "how good of an" construction is traditionally actually considered less acceptable. I'll link to some related questions in a following comment. – sumelic Aug 17 '18 at 23:04
