shared prong eternities vs uprongs

[ringsearching]

do shared prong eternity styles tend to have a more pinched in prong look than u- prongs? meaning does each stone look a little more rounded when viewed face on? I can't decide if I am imagining that or not. I love the uprong side profile, but the more rounded look of each diamond. is this observations correct? or my imagination? and are there differences in the u-prong look of idj, erd, bgd and whiteflash? I trust the experts who have owned some of these and have a better eye more than myself?
