Nikon F Photomic with the Incidence Attachment in place cannot be beat, IMO, if you must use an in-camera meter.
I see no big advantage in cameras that have various metering patterns. It doesn't matter what your metering pattern is because it is still a reflected light meter, therefore is very sensitive to changes in composition. An incident meter only responds to changes in the over all lighting condition. This makes more sense to me. Reflected meters are fine, but you always have to be on your toes when using them, and constantly making adjustments based on what they say. You can follow an incident meter directly and have a higher rate of ideal exposures.
If I were to pick an in-camera reflected meter that I like best, it would be the Canon F series, like the F-1 and FTb. Only the center patch meters, making it much easier to arrive at the right exposure, IMO. Averaging, evaluative, center-weighted, etc. meters are not as easy to use to meter only a section of the scene, and spot meters are small and error prone if you are not taking your time. I find the Canon 12% patch to be a good compromise.
