I have a 128 GB Strix Halo tablet (same as the other commenter here with the Framework Desktop). I'm using the larger Gemma 4 26B-A4B model (only 28 GB @ Q8) and it's been working great and runs very fast.

It's a 100% replacement for free ChatGPT/Gemini.

Compared to the paid pro/thinking models... Gemma does have reasoning, and I have used the reasoning mode for some tax & legal/accounting advice recently as well as other misc problems. It's worked well for that, but I haven't tried any real difficult tasks. From what I've heard re. agentic coding, the open weight models are ~18-24 months behind Anthropic & Google's SOTA.

Qwen 3.5 122B-A10B should just fit into 128 GB with a Q4/5 and may be a bit smarter. There's apparently also a similar sized Gemma 4 model but they haven't released it yet, the 26B was the largest released.
