Hmm... I don't dislike felines, but I must admit that the way the model is built gives an impression of bulkiness to it, even on the lowest weight setting. Then there's the problem that on the lowest weight setting, you have some manes that have transparent gaps where they're supposed to be attached to the body (this is most visible when lying down).
The wolf model, has a better variation of the weight slider; you can go from a husky-like canine, to a more slender, near greyhound variant, while the feline one scales pretty much the same all around the body. There's also the fact that the wolf model has the option to be without a tail, whereas the feline one pretty much has two of the same options (both the lynx and tailless options share the same model).
The manes on the canine appeal to me a lot more than the ones on the felines; the only one on felines that I actually think looks nice is the center half mane. The wings are also a problem, (hence why I liked FH better without wings) since they "stick out" more on the back of the feline model than they do on the canine.
Overall, I like the canine model better because of its customization options and elegant look. I have a preference towards canines in both real life and roleplay, don't get me wrong, I have absolutely nothing against felines, but by personal preference, I have to go with canines.
