Anime Tsukune isn't even worth mentioning.
Manga Tsukune, I can't really call him GAR. He stands up to his opponents and is just a bit braver than most other people, not to mention decisive as a harem protagonist, but beyond these qualities he's pretty unexceptional. The circumstances of the manga still push him toward indecision to make it interesting, and if he wasn't brave he wouldn't be at the school at all, so there wouldn't be a story.
I mean, as far as getting his powers go, he didn't earn them, he was given them. And he doesn't really use any strategy with them, he just uses the power rawly.
