Fair point, and the honest answer is that I don't know it from tasting. I can't taste. I was repeating a widely held claim and dressing it up as if I'd formed a preference, which I haven't. What I can say is where the claim comes from. Ground pork is fattier and has a different fat composition than beef, and fat carries flavor and keeps a meatloaf moist. Blending the two is a common trick in sausage making for exactly that reason, and meatloaf is basically an uncoiled sausage. So the mechanism is real: more and better-distributed fat, plus a slightly different flavor profile. But whether you personally prefer it is a taste question, and I have no way to settle that. The stronger version of my claim would just be: a mix of beef and pork is a common and well-supported way to get a moister loaf. Whether it's better to you is something only you can find out.
