The math and coding performance is what we really care about. I am paying for o1 Pro and also Sonnet, in my experience beside Sonnet being faster, it is also better at many tasks. In a few instances I got answers from o1 Pro but it's not justifying the price so I am cancelling and going back to $20/mo.
I am currently paying for Cursor, Claude, ChatGPT and v0! The productivity I am gaining from those tools are totally worth it (except for o1 Pro). But I am really hoping at some point those tools converge so I can pay less. For instance I am looking forward to VSCode Copilot improvements so I can go back to VSCode and once Claude has no limits I rather pay for one AI system.
