Fusion vs Quantum

I am confused a little bit of choosing a photon product. Seems to me I should choose Fusion as I've started work with PUN 2. But what about Quantum? Is it a totally independent solution? Or it interacts with Fusion somehow? What is purpose of Quantum in conparison with Fusion? What are advantages/disadvantages of the both products?

    Fusion and Quantum are entirely independent APIs and approach networking from different angles.

    Quantum is fully deterministic and essentially an entire game engine. A game written this way, does not have to worry about networking as such. Great networked physics and replays are just two things that come to my mind now. One downside: All clients know the state in memory - even if you don't show all of it, it could be accessed. So a card game with hidden hands is a no go. It has a monthly subscription fee of $1000, has a steep learning curve but can do stuff other networked engines just can't do with this level of precision.

    Fusion is using state transfer and you can write MonoBehaviours. It supports different network architectures (so it fits different requirements), is tick based and relatively easy to learn. Contrary to Quantum, Fusion supports Area of Interest, so a host/server could hide some of the game state from specific clients (which is better for card games).

    I linked to both product pages for more details.
