Diamond won and Brunswick lost- end of story. Brunswick’s most recent attempt to come back into the market at such a high price point with Chinese tables is a joke, IMO . Maybe the 7 plays like a Diamond IDK - but Brunswick lost their way in pool way back in the 80s /90s as a possible future leader that just let it all slip away concerning their billiard business.
I personally will not support Brunswick’s recent forays and refused to invest in a 7 for my new home- I am not a Diamond guy- so I went with a 3, the last ones made here in America.
