If you're only going to pay one $20/month subscription I think OpenAI wins at the moment - their search tools are better and their voice chat interface is better too.

I personally prefer the Claude models but they don't offer quite as rich a set of extra features.

If you want to save money, consider getting API accounts with them and spending money that way. My combined API bill across OpenAI, Anthropic and Gemini rarely comes to more than about $10/month.
