TTGL was one of the first anime's I had watched. Although it was one of the first, and I've seen many since; it will forever be in my top 2. The only anime to ever pass Gurren Lagann as my favorite anime of all time is Kill la Kill, and that's just because it was even more over the top.
I watched the dub, mostly because Kyle Hebert is my favorite voice actor, but I recommend both the dub and the sub, both are great.
I completely recommend this anime to whoever is seeking a thrill and one hell of a story.
