I have recently switched to Swarm as well. I must say that the pink fuse is really good for Swarm.
If you have your accesories stage 10 you can swap them for (basically) free. Only thing that would cost you some time to swap is the bracelet. At the end of the day its what you prefer to play. I believe that Swarm is better now and that it is worth switching to that is what I have experienced.
