I own both CC3+ and Fractal Mapper so I’ve got a pretty good idea of the end results (and how much work that can require, btw 😉 ). 🙂
But where the price is involved Fractal Mapper is cheaper no matter what. CC3’s total cost with add-ons is several hundreds GBP : . While you can have the full fractal mapper suite for like 50 USD, 30 or so for the basic soft, iirc
