With what AI models have you had the most wow-moments?

I wonder with the models of which provider or architecture had you experienced the most of wow-moments? Iterative improvements of a certain model should not be separated.

I, personally, had the most of wow-moments with Claude. On the second place is GPT, and the third place takes DeepSeek (mostly fo open thinking).

I have experienced exactly zero wow-moments with Gemini and Grok, as well as variations of Llama.
