Darling in the Franxxx was my first mecha anime! (unless you wanna' count bits of Gundam that I used to see on Toonami when I was a little kid) It was a very fun watch. Monogatari and the Fate series are in my top favorites for sure. I've seen all of Monogatari, but I've only seen Fate Zero and Fate: Stay Night - Unlimited Bladeworks. Judging from your favorites it sounds like you might like both shows. Monogatari is suuuper dialogue heavy and honestly so eccentric that it's a "love it or hate it" kinda' deal, but a very rewarding and entertaining show imo. Fate is more balanced with quite a lot more action, especially as you get later into each season it really ramps up. The watch-orders for Fate / Monogatari are kind of complicated. I'd Google one for the Fate series, but I can tell you how to watch Monogatari. The issue with Monogatari is unless you sail the high seas or something, I dunno' how you'll find everything. Crunchyroll only has Bakemonogatari and Nisemonogatari iirc... I had to buy the Kizumonogatari 3-part movie on blu-ray through rightstuf anime, and that's literally the second thing you're supposed to watch. Fate is a bit more accessible in this regard, but you might uhh know the right places to look and might not have this problem with Monogatari. I personally loved Bakemonogatari so much that I just bought the entire show on blu-ray which cost, like, a lot. Was worth it though; I love that show. I've got a nice little collection going.
