Excuse my ignorance, but is the good experience somehow influenced by Google AI Studio as well or only by the capability of the model itself? I know Gemini 2.5

Excuse my ignorance, but is the good experience somehow influenced by Google AI Studio as well or only by the capability of the model itself? I know Gemini 2.5 is good, have been using it myself for a while. I still switch between Sonnet and Gemini, because I feel Claude code does some things better.
