From my experience, qwen3-coder is way better. I only have gpt-oss:20b installed to make a few more tests but I give it a program to make a summary of what it does and qwen3 just works in a few seconds, while gpt-oss was cancelled after 5 minuts... doing nothing.
So I just use qwen3. Fast and great ouput. If for some reason I don't get what I need, I might use search engines or Perplexity.
I have a 10GB 3080 and Ryzen 3600x with 32gb of RAM.
Qwen3-coder is amazing. Best I used so far.
