If you're wanting to give One Piece a shot, the manga is far and away better than any adaptation, but if that's not your thing you can check out the "One Pace" fan edit which has the goal of trying to make the anime more accurate and cuts out filler stuff.

I think Inaki does a good job of capturing Luffy's energy, it's really difficult to portray a character who's personality is cheerful and carefree without making it super cheesy, although I think it went over the line a few times when combined with the dialogue and line reads they used.
