There is a magical quant GSQ-RCO that at 3-bit XS beats the full unquant. I have tested it. It is on par with the full unquant on DeepSWE. Give it a shot, it is magical. ITSA lab, they basically devised a way to selectively quantize parameters. I am a GSQ-RCO truther at this point... it is so fast on my V100s and I can't find an instance where it has acted weird or fell short of the full quant on agentic coding. I Have it 3d model in blender, all sorts of stuff. It's just... good.
