Dear teachers,

I am interested in knowing whether the 'of …' in the sentences below are being used in everyday talks in english speaking countries or whether it is used mainly in written form..
:
He did not make much of an impression.
He mistakenly feels that what others have to offer him is of no value.



Thank you

"He did not make much of an impression.

These are perfectly normal and natural in speech.
