I was only introduced to Solar, Magnus and Turok through the Valiant Comics. I kinda liked how Valiant weaved the story in between the characters. Unity is actually one of my favorite story arcs in the Valiant universe. The way they made Phil Seleski turn to be exactly like his childhood hero Dr. Solar, and how they explained the capabilities of Magnus through the fact that he was the child of the Harbinger Torque.
It was a shame that Valiant shut down. Even though the weren't as successful as the other publishers, the story they produced are top notch for me. They don't need to rely on gimmicks, they had a solid story to tell. Although later on they did jump on the gimmicks band wagon. I still own several Valiant comics, including the first appearance of Ninjak, which was worth quite a sum of amount, buy now probably worth a buck or two.
