2 weeks since the release of Gemma 4 12b Unified, how are we feeling about it?

I'm looking for a good model to run on a 5090 and have ample context ~128k. This model looks good for me, it seems to have good performance in the 12b range, almost comparable to Gemma 4 26B A4B. Building a custom harness for it and have ~300m of tokens to fine tune on. Do you think this is the best option for me on a single 5090?

Edit: Also suggestions of quant, unsloth variants, etc. etc. etc. are appreciated. I have a hard time tracking all these.
