first of all, those people are 12 year old horndogs, they rank it low cuz it's not hentai, they know shit about good stuff, and will likely never see a real live pussy, and if they will, it probably will be soon before being arrested.
on topic though, I don't know about romance, I didn't notice all that much of it in this show, and I will not put up a flame shield, cuz I simply don't care about other's opinions on that but I think Da Capo had a ton more romance that Yosuga no Sora,
simply because you can't expect a lot of romance in a 2-4 episode arcs where everything is packed and compressed, the game has a shitload of scenes where you can actually see the romance building up and then bursting inside the girls (literally, the game is quite explicit) so,
no, the show doesn't have much romantic scenes, it has what the people wanted to see well animated, raw sex, every few episodes, silly censored at that, if you want to watch it for the sex, do the BDs,
if you are actually interested in the good sides of the actual story in the show, you can watch the TV version, it will still have enough of sex to satisfy your lust, and curiosity, Although, Sora's arc beats the rest with a simple slash of a spoon.
