I now have both M2 and M6. The M6 meter is accurate and reliable. BUT you do need to squint down the viewfinder and aim the camera at what you want to meter and you can miss a lot of shots doing this. The MR meter on the M2 is just as accurate and you can clip it to the top of the camera or keep it in your pocket and take very discreet readings, put readings on camera, then it's really quick to put camera to eye and take the photo. It does depend on what you are photographing but with people and negative film either B+W or colour I reckon you will get fewer failures from exposure errors than from not being ready to press the shutter button. Photographing buildings/landscape with reversal film though meter as much as you want.
