I've only owned one Taichung spyderco and two Golden's, but in my experience the fit and finish on the Taichung models is several notches above Golden. My Manix 2 LW had no real problems, but the FRN handles were a bit "flexy" and the action was always gritty even after months of daily carry. My PM2 has always had blade play that I can't adjust out without making it too stiff to flick open. I've spent hours trying to tune it following all the guides posted around BF, but I never could get it just right.
My Domino is smoother than both, has many more technical/high end touches (chamfered edges, bearings, lockbar insert, Ti/CF, etc) and is totally free of blade play. I can't say definitively without handling more models from each factory, but it's pretty clear for me. Taichung makes higher-end knives to a much higher level of fit and finish than Golden. Of course, you do pay more for that extra F&F and the fancy components.
