Gonna second the recommendation for Symphogear, at least the first season. I haven't actually managed to watch the second (or third) yet, so I can't say much about them.

If you need the full title, it's Senki Zesshou Symphogear. Season 2 is G, and 3 is GX, which is still in the process of being released - I believe there are six episodes currently available, with a seventh on the way? Correct me if I'm wrong.

I can provide links to streams on request, if you don't mind using an ad blocker. Or I'm sure someone else can provide something more legitimate.
