My first real 35mm camera was a Pentax SP 500. Eventually added a Pentax ES, screw mount cameras. I made great pictures with these cameras. Just matched up the needle, or with the ES set to auto. I had to be cool so I traded these in for Nikon F2S, this camera is more center weighted. I bet my color slide success rate dropped by 75%. I rarely use in camera meters unless it's something like a Nikon F5 with matrix metering on auto pilot. I'm better off guessing. I'm actually pretty good at guessing. I use an incident meter. Pretty boring approach
