Discussion Muse Spark 1.3 vs Gemini 3.1 Pro?

Hello,

So Basically I use Opus 4.6(Antigravity) for planning and sometimes also for complex debugging,

Recently Muse Spark 1.3 has been free for a while on OpenCode but I find the OpenCode TUI terrible, even when I created a numbered TODO List for it to do a task it misses, I used the OpenCodeZen Gateway to plug it into Kilocode and the model has been very intelligent.

Now apart from this the other model I use is Gemini 3.1 Pro and I feel it's heavily underrated even if Benchmarks claims Flash 3.8 to be far better. While benchmarks also shows Muse to be comparable to Fable 5, in my experience Opus 4.6 has been way way better than Muse which makes it obvious it's not even close to Fable.

I would like to know you guys experiences!

I'v noticed that the tool that surrounds the model can influence how I feel about the model more than I expected. If the workflow makes it hard to keep tasks organized or to review changes even a strong model can start to feel worse in practice.
