I suspect that the main difference between the two is that while magic system can differ greatly from one work to another (e.g., relying on the ambient mana in the surroundings vs. relying on one's own supply of mana, activation via long chants and calculations vs. activation via hand gestures, etc.), the psionic powers tend to be quite uniform.

And if we go up the power-ladder, we eventually reach a variation of omnipotence with both paths, so that's that. However, if we compare common examples, then magic usually has greater versatility than its psionic counterpart. This also often means that the psionic power is more readily available to the user than its magic counterpart, because one commonly starts with nothing but an aptitude toward magic or some particular magic and needs to study and acquire or devise spells before there is anything to show.
