In my opinion no frontier model is the best at everything, especially if you're having to catch it up with pre-existing information about your project or an esoteric scripting language, that being said, with Cursor you can try out all of the popular available models and get a feel for which do better with which tasks, in my experience - Codex is a okay model but use light thinking if you value your time, Gemini 3 flash is where its been at for me recently if I need to do big changes I go to that, And cursors model composer is good for making plans or doing refactors / making rules. Cursor gives you tools to make prompting feel like less of a repetition game, so you worry more about the task at hand and its been super efficient for me. I don't use proper version control so the fact it saves a history of every files dif's, and you can jump back easily in chats and regress the code base is the game changer.
