12 man for 3 and cots.
even with out cots you will be better off with the 12 or the courthouse. 3 fit ok in an 8 man without cots but 3 in a six is just an emergency.
i have had two 8 man tipis and sold them. i keep a six for 2 guys when weight is a factor and a 12 if weight if not a factor or there is more than 2 guys.
