Happy to elaborate. I have no dog in the hunt from a technological standpoint, as I currently own DD, belt drive and idler drive turntables and do not feel that either technology is superior. And, not having heard the G, my comments only apply to the 1200/2 which I am very familiar with. So that may invalidate my comments from the git go.
I found the sound of the Technics rather clanky which doesn’t work for me. Is it the arm? I’m no material scientist, couldn’t tell you. Maybe the G is better in this regard. I did put an SP-25 motor unit in a Baltic birch CLD plinth with an AT arm long ago. As that is the same motor unit as the 1200 and I did not hear those colorations, I would conclude that there is a likelihood that it is the base or the arm that is contributing the sound that I don’t care for. And that may have been attended to in the intervening time.
The Rega doesn’t quite get the silence between the notes right and the Rega arm is a bit too controlled in the upper midrange for me so it has issues as well. And the lack of fine VTA adjustment is a serious flaw in a product at this price point. But everything is flawed and we make our choices. It would be best, and probably impossible, to audition both.
All of that said, I would spend my money on a Linn LP12 as it just does more that is correct to my ear. YMMV, and good luck with the hunt.
