Mistral Small 4 vs Nemotron 3 Super for agentic coding?

Looking for a local model for opencode on two DGX Sparks, mostly C#/.NET code. Benchmarks I've found put Small 4 behind Nemotron 3 Super, but I'd like real-world experience: is Small 4 good for coding and tool calling, and has anyone compared the two?
Thanks!
