Yes: the satisfaction of
knowing light without using a light meter, applying the 'Sunny 16 Rule' in lighting situations for your desired choice of shutter-speed and aperture, from dazzling sunshine, to dark, gloomy interiors of buildings.
With digital cameras, particularly older/earlier ones, you can work out the camera's true ISO for its base sensitivity. With old Nikon DSLRs like the D1/D100 era '200 ISO on the camera' equates more accurately to an ISO/ASA rating of 80-100. ISO/ASA 200 equates more accurately to ISO 400-500 on the camera - depending on whether the scene is lit by direct daylight or whether there is only low ambient or artificial interior light. You get to know a digital camera's sensor capability in this way and compensate for it.
I calculate Sunny 16 in my mind always in terms of a baseline 200ASA and 1/200th second shutter speed. So I judge ambient lighting in terms of 'f-stop': f22, f16, f11, f8..down to the theoretical 'f1' and beyond into imaginary '-f1', '-f1.4' etc. You can practise this in your mind anywhere you go, without a camera: I'm in a darkened room partially lit by distant window light, thirty minutes after sunset, and I estimate the light is three to four stops below f1 (at 200asa, 1/200th second). So I compute the shutter speed for say f4 (max aperture or desired DOF of my lens), and camera 1600ISO, (~'800' ASA in actuality). With a lot of experimenting and practise it becomes reliable and you can always bracket exposures.
Its empowering also to learn how to fill and bounce flash manually, (learn to use your flash's 'guide number', learn to judge distances, learn how materials on and near the light path absorb and reflect the light from your flash, and how filters additionally reduce light - 'filter factor').
