Given the hedges made in your statement here and the extremely questionable choice to trade a Q4 model with a less quantized cache for a Q6 with a Q3 cache I think this can safely be said to not fit the title.

The Qwen3.6-35B model has, in my testing, been decent but not nearly as good as the Qwen3.6-27B. Running that with a less quantized cache is going to be "better" for anyone using it for software dev in my limited testing.
