On the Kings: I like the V-neck on both, but the black-and-white piping on the old one made it look a little dated. Removing that was a good idea. It looks more modern.
Even though it's purple, I can see the new version being a more commonly purchased jersey. It's an appealing design that you could wear without drawing too much attention to yourself. I mean, you want to support your home team, but it sure helps when it looks put together, right? (Ed. Note: Um, I guess.)
Maybe it's just the photos you selected, but the fit of the new jersey is a lot closer to the body, which makes the older one look sloppier by comparison. Did they take it in at the sides to accentuate the waist?
Overall, the new look is a nice, simple upgrade.
