I guess I've been around animation for so long that the art style of KLK doesn't even phase me.
Kill la Kill is less blatantly fan service-y than Panty and Stocking was, but there's still a huge amount of panty shots, gratuitiously bouncing breasts, nudity obscured by convenient lens flare and random dick jokes. Which is not entirely unexpected, it's basically the same people making it.
Gurren Lagann had it to a degree in Yoko-heavy episodes as well, but it was less obvious because so much of the show was spent with guys striking dramatic poses that there wasn't much time left for titty-wiggling.
I dunno, if I want to see Ryuko's boobies I'll go read some doujinshi. There's a point at which too much in the show just gets distracting to me.
