For cameras of this age, the most important factor is not their original feature set but their present condition. With older film SLRs, reliability and usability today will usually matter far more than small differences in specifications when new.

When comparing these models, prioritize:

• overall working condition
• shutter and film advance operation
• meter/electronics function
• battery compartment condition
• light seals and general wear
• lens mount condition and lens availability

A camera in excellent working order will usually be a better choice than a more advanced model with age-related faults. That is especially true with older electronic film cameras, where failures can make them difficult or impractical to use.

So the best comparison is less "which model was better on paper?" and more "which individual body is confirmed to work properly and is in the best condition?" If buying one, ask for proof that it meters correctly, fires at all speeds, advances film properly, and has no corrosion or major mechanical issues.
