I had both for a while and my metro was the older make. I sold the metro. Balance was different. Overall sound complexity of the two bows were really similar even though the metro had black hair while the glasser has white. In comparison, the glasser was a tad brighter, louder and the tone was organ-like true. The metro sounded scratchy which is why I sold it. My primary bow today has black hair which gives it that presence edge, but nothing like the metro. The frog on the glasser was a little bigger. Stick length the glasser is a little longer. The glasser is a little heavier in the tip than the metro. Kept the glasser even though I rarely use it since I got an old french grip German shop bow which I love (my primary bow today). If you are interested in one, I may part with it. PM me. I don't want to derail your topic.
The glasser is a really good bow and its nice to see the fondness for it in this thread. I just applied some rosin due to this thread to it and played for 10 minutes. It is loud and powerful, for sure, and I really appreciate it in my collection.
Here is a Metro sample here from when I sold it:
