Who's older? Donatello or Raphael?

[Refractive Reflections]

(I want to apologize beforehand if this thread was already posted, but I tried searching for it and couldn't find a specific thread for it.)

I know there have been numerous threads about the age of the Turtles in general, but I was more curious about the birth order of the Turtles. We all know that Leonardo is the oldest and that Michelangelo is the youngest, or at that very least if some versions don't mention that, it seems to imply that.

Therefore it leaves Donatello and Raphael as the middle children, but between them...who's older? Was it ever resolved official by Eastman and Laird? What do you (as a fan) think yourself?

In my small opinion, I get the impression that Donatello was 2nd and Raphael was 3rd because some of Raphael's anger issues may reside in that he is constantly living under the shadow of his more older "accomplished" brothers. With Leonardo excelling in ninjutsu/leadership/athleticism and Donatello in science/academics, it makes it more difficult for Raphael to uniquely shine in his own right with his talents and abilities; thus making Raphael feel like he's being compared to them despite Splinter and the other Turtles not doing so. In fact, it seems like most versions of TMNT seem to focus (not always, but mostly) on Raphael's emotions rather than any unique combating skills (besides his strength and hot-temper) that make pivotal contributions to the Turtles' missions.
