I started with Tamrons,getting f2,8 trio at first (17-28/2.8,28-75/2.8,70-180/2.8).I was not lucky,as three subsequent copies of 70-180/2.8 that I used to have were badly decentered.I did not like also the overall plastic feeling of the trio,but first of all didn't like their colour rendition.All that made me shift to Sigma (14-24/2.8 Art,24-70/2.8 Art,Contemporary 100-400/4.5-6.3).This was better combo overall,yet after sometime 24-70/2.8 developed rattling inside,which i could not accept and 100-400/4.5-6.3 had poor image stabilization and contrast at 300-400mm.All of the above Sigmas fared better than Tamrons for me,yet despite all their merits I was not satisfied with their colour rendition still.Finally I decided to change them for Sony GMs 12-24/2.8+24-70/2.8+70-200/2.8 Mk1 and this was a good move.I like Sony GMs most.Upgrading from GM 70-200/2.8 MK1 to MK2 increased my satisfaction even more (better overall IQ+lower weight).

I'm surprised you say colour was a reason to change to GM's. First of all you have very good postprocessing (i would love to know the basic of it, i have a different style, but i wanna have as much power over colours in postprocessing as you have). As a result both your Sigma and GM results are beautiful.
Secondly, the 24-70mm GM is my biggest dissapointment lens. It aint sharp except at 35-46mm (my copy), the colours are boring, it was a complete first production copy though (like 1 year after release), i bought it used way below new price. But it didnt fall or have decentering. The colours were meh. 24mm GM has waaay better colours, 100-400mm gm as well, and as such even the Sigma 24-70mm dg dn has better colours.
But yes i agree the GM II are amazing zoom (well 24-70mm GM II we must see yet but i'm hopefull it will).
Is your 12-24mm GM sharper then Sigma 14-24mm dg dn? At 24mm the sigma is incredible sharp (same as GM 24mm) but at 14mm i'm having mixed results, sometimes asigmatism or something else. In theory 12-24mm gm is prime sharp at 18mm and little softer at both ends but this could be different in practise. One review has incredible sharpness at 12mm F4, so i'm curious.
