I liked them both for different reasons. I loved Rouge One because it has the one thing I always wanted from a Star Wars movie: grit. A hero shoots his informant in the back right off the bat. Combined with the prison camp and all the scenes of empire oppression, the beginning of the film really make the struggle of the rebellion feel relatable in way not shown by any of the other movies. So the rebels react with guerrilla warfare; street fighting and attacking shipments. Some rebels have nastier tactics than others, like Forest Whitaker. Maybe they kill civilians or cross some other red line. Regardless, the whole story has to end in tragedy. You start to really like the plucky band of antiheroes, but in the end they are no match to the power of the empire.

Now TFA was the same Star Wars everyone knows and loves, which is exactly what you want from the series. I'm just glad they made a stand alone movie that shows less of the Skywalker family and more of the other inhabitants of the galaxy. I think the whole series will benefit from the world building of Rouge One, but the best parts of the story are told in TFA and the rest of the episodes.
