All the other are saying to you right things. The study cited by Apex was talking about this 3% difference per each level (as far as I remember, still not impressive), even though they were suggesting a potential higher cross training effect besides the "normal" one.
All that said, it's still true that clinching higher levels sooner, if properly managed, will enhance your elastic effect on other skills giving you an additional advantage over time.
