I think that Rogue Trader will totally be the better game. I already think that WotR is the better game by miles. As for romance, it's not something I'd have thought to compare between the two games but now you mention it, while I don't need all companions to be romanceable at all, Owlcat is still demonstrating a less than ideal balance in their romance options. 3/4 romances, with only one same sex woman romanced by women and no same sex male romance. I'm happy with both the Larian and Owlcat approaches but I do find ommissions like that to be a touch disappointing, and I feel a little bad for anyone who would have wanted a male/male romance.
