i think you nailed it, there really isn't much of a difference, unless you like one over the other,
then you will always notice the difference you decide there is.
i really can't tell from your uploads. i am guessing that if they were both printed the same
focused the same, toned the same and photographed the same ( without flash glare ) they would look sort of the same.
me, it really doesn't matter much fb or rc. both look nice to my eyes, i like the convenience of RC but i also like
being part of that 170 year continum printing on paper ... but that is just me.
some folks love rc some fb and they are hardcore about why one is better than the other
rc is great stuff these days, even if you are talking archival-stuff. kodak told me it will last longer than FB.
good to see you having fun !
