If you are measuring with the Gossen in reflected mode, comparing to a weighted metering from a camera, be very careful that the metered "target" is evenly illuminated and a consistent texture/color. From what you have described, I think your new Gossen is spot-on accurate, and the measurements from your DSLR I believe confirm that.

It is hard to debate the quality of an incident reading, one argument might be that "I can't get in front of the subject to take a reading", but I would counter with the fact that if I move within some part of a 360 deg. circle I will find a pretty accurate substitute. Stage lighting, and situations like that are different, but in an area with pretty broad luminance incident metering is a great start. Do get the APUG article on incident metering, it is a worthwhile read.
Over the weekend, go outside and take some readings with the Gossen in both modes, you will learn a lot through usage.
