Maybe Natsu's "lessons" with Igneel were just further ahead of what Metallica taught Gajeel, so his body wasn't fully "adapted" to the Dragon Slayer magic, and Gajeel's self training not only made him more powerful, but also made him more "dragon-like." We know Wendy still has two major Sky Magic spells to learn, but we really don't know much Gajeel's training.
I would note that Natsu is the only one of the Dragon Slayers to undergo "Dragon Force," so its possible he really is the most advanced of the Fairy Tail dragon slayers in their brand of magic.
Then again, it could all just be the "rule of funny."
