Re: Compare and contrast M5 and M6(non-TTL) 0.85
The M5 works for me. It is heavier and bulkier, but that is made up for by the spot-on metering and the fact that the speed dial is so easy to set with the camera to my eye. Mine has been upgraded for modern batteries, so that is not an issue.
Since you have an opportunity coming up to use an M5 for a couple of weeks, I would wait till after that to make a decision.
