Gemma 4 - MLX doesn't seem better than GGUF

Going to flag this up front - I know that there are some properly smart people on this sub, please can you correct my noob user errors or misunderstandings and educate my ass. Model: google/gemma-4-26b-a4b Versions: MLX: GGUF: Prompt: I have been testing a prompt out with Gemma, it is around 3k tokens, comprised of: Full script of code. I've cherry picked the part that is relevant to my question (a Python function that uses subprocess to launch a Streamlit dashboard). Question on some Streamlit functionality (what is the argument to set a specific port). Basic stuff.
