For this I’m going to go with my SHL team that I don’t yet play for but I think has the much bigger rivalry. The clear answer is the San Francisco Pride vs the Los Angeles Panthers. The reasons for this rivalry are pretty obvious. Not only are these teams both located in California, which tends to have some heated matchups, both of the teams are big cat related. I think that the fact that the teams are so close that it would lead to a massive rivalry that would contest any playoff based rivalry. The market of cat related hockey merch is on the line and the players and fans need to support the teams to ensure the success of their corporate owners. It also is important to mention that panthers are barely even a really thing, assuming you mean a jaguar then a lion would nearly DOUBLE the weight of a panther which it would easily demolish.
