The best way is to get large samples, or sample pots, and stick them up in your home. Online digital photos have a lot of variables so you can't judge a paint colour by a digital image. Your windows, your lighting and the colour of your floor finishes will all affect your perception of these lighter greys. If you are getting samples then I would also consider the half strengths and full strengths of both colours. You will be surprised how your perception of these colours will change when they are vertical in your home.

Best of luck
