Say I'm playing a song in C Minor, and I play the chords

Cm, B♭, A♭, G

If I was talking about, or analyzing these chords using roman numerals, which way is more correct to refer to them?

i, VII, VI, V

 

(because B♭ is the 7th step of the C minor scale, etc.)

or

i, ♭VII, ♭VI, V

 

(because when talking about chord numbers, you assume that the numbers refer to degrees of the major scale, so a VII would refer to a B natural major)
