I haven't been keeping up with KingOhger but it's certainly more focused on story while also being pretty popular with the Gays, Kyuranger has a rough start due to the red's obnoxious attitude but if you can sit through the first like, 10 episodes no problem and accept that not every character's gonna get focus due to the stupidly large cast, you'll probably enjoy it. Gokaiger though? It's good, but a lot of it is just celebrating the series with all the cameos of past rangers so while you'll be given a lot more context than anything Donbrothers did, you're at the wrong place if you want more original stuff. While it's not exactly a fantastical setting, may I recommend Dekaranger? It's a fan favourite for good reason and stands out very well due to it's unique quirks, especially when it plays up the cop show angle. ToQGer might be perfect though if you want full on unadulterated whimsical joy, it has it's serious moments sure, but it's still really good and has my personal favourite pink in the series and the Least Heterosexual 6th ranger I have ever seen
