Same opinion. Opus is best for coding, but Qwen 3.6 27b Q8 is next, before Sonnet.

Sonnet might have more knowledge and is maybe good for making excel sheets, but it does not write good code and does not follow instructions well.

But 27b Q8 needs a very beefy PC (48GB VRAM or more), so it is not an option many people can use and DS4F is so cheap right now, if you are open to externally hosted models.
