RX100 or similar point and shoot for people that want high quality versatile pocketable camera but don't necessarily care for swapping out lenses or carrying around a bunch of gear
A6000 or similar for people that want DSLR-ish quality and to be able to swap out lenses but don't want a huge bulky package
Superzooms for those that value insane amount of reach without spending buttloads of money and dont mind carrying around their gear
tons of mirrorless and DSLR camera systems are out there for amateurs, enthusiasts, professionals... but even then, I don't think you can define a "best camera" as the answer to that question will always depend so heavily on the use case / desired outcome. Even between two professional photographers, the best camera system for each one could be very different.
