I agree with Carry.

Silver's last words might (emotionally) sustain Gray until the moment END is defeated, but then they lose any meaning.

Igneel's words on the other hand will have meaning for Natsu until the day he dies, maybe even beyond that through Natsu's children.

Sure Igneel didn't have a gift-wrapped power-up for Natsu, but that was never the point Carry made in the first palce. It was all about the words alone.
