Both 'Gurren Lagann' and 'Space Dandy'.
They're (pretty popular) Anime series, just in case there's someone out there wondering "what the hell is that?"
I would say that I generally like Anime, but nothing with.... "fan service". That's the nice way of saying that Anime has a penchant for hyper-sexualized depictions of women, and I'm not someone who is going to recommend shows designed to be "fap material". I'm drawn to shows for the premise and the narrative more than big jiggly animated tits. I'll tolerate some ridiculous improbable breasts in a good show (because there's really no escaping them in this medium), but I find most of the shows with a "battle high school" or "nerdy guy surrounded by hundreds of impossibly hot co-eds" to be tedious, boring and frankly a bit embarassing. I'm not about to send you guys off to watch "Trapped on the Island of Bikini Babes 9".
With all of that said:
One note about Gurren Lagann: you absolutely must watch this show in Japanese with subtitles. It's not because I'm some Anime Hipster telling you that Japanese is always better than English, it's entirely because of the character 'Kamina'. The Japanese voice actor for Kamina defines the character. It's not what Kamina says, but the voice with which he says it that makes his every moment onscreen an absolute joy. There's also this crazy signature war-cry that the Japanese voice actor does before all of Kamina's ridiculous speeches that the English voice actor doesn't attempt to re-create. The result is two very different characters that share the same face. One of them attempts to shout down a giant robot using only the power of a silly war cry and unshakable confidence; the other stands in the exact same spot and says "Hey! You big dumb robot! Get outta here! Nobody smashes up my village!". It's not exactly hard to decide between the two versions. The English dub is a good dub as far as Anime goes, but nobody captures the insane enthusiasm of the character like the original Japanese voice actor.
That's pretty much everything you need to know about Gurren Lagann going into it. It's on Netflix as of this writing, if you want to go watch it right now. I'm pretty certain you won't even need to give it the old "three episode test"; if you're not even a little bit interested by the end of the first episode, I'm pretty sure you're a robot.
