What seems clear is there is no consensus. Gemini 2.5 Pro just seems consistently worse to me, but I’ve seen others sing its praises. This might be more like iPhone vs Android than a true stack ranking of models.
I don't have that with Claude-Code, it just keeps on chugging along.
One big difference there though: I got the Claude-Code Pro Max plan (or whatever it's called). I now no longer have to worry about the cost since it's a monthly flat-fee, so if it makes a mistake it doesn't make me angry, since the mistake didn't cost me 5 euros.
I am using an MCP server that adds Gemini & O3 to Claude-Code, so Claude-Code can ask them for assistance here and there, and in this Gemini 2.5 Pro has been such a great help. Especially because its context size is so much larger, it can take in a lot more files than Claude can, so it's better at spotting mistakes.
