Well.......best is a relative thing.
There is no perfect camera.
Getting manual controls on an ultra thin camera is scarce as hens teeth.
I know of only 2:
Casio Z500
Fujifilm F11
Both of these are very new and you are not likely to find any reviews yet.
The F11 is not yet available in the USA.
But it is an F10 with manual controls.
You might find a review of the F10 somewhere.
