Your reply made me go wiki-walk the fandom wiki for Yona of the Dawn...and remember some of the more dramatic moments, the memory of which nearly brought tears to my eyes. Indeed, it's excellent.

Cross Ange is...quite different an experience, to say the least. Its "fanservice" -- more like sexual elements, more generally -- is integrated into its plot, with at least some of it an intentional portrayal of the demeaning circumstances that horrible people force onto others. More generally, the show doesn't at all shy away from particularly harsh storytelling, themes, and social commentary. In stark contrast to the subtleties and elegance of Yona of the Dawn, Cross Ange's storytelling takes a more aggressive, uncompromising, and at times savage style. The result is a much more viscerally emotional experience, which I'll admit isn't everyone's cup of tea. Opinions on it vary between those that hate it, those that think it's hot garbage but ironically awesome, and those (like myself) that unironically think it's an excellent work.
