So, I think I'd go to ChatGPT first and if the result is good enough, then I can skip Bard.
Seeing the development of the AI, probably it is good to check other solutions from time to time. Probably there will be better solutions over time. And probably the ChatGPT and the Bard will also be improved over time. And the results can also be different from task to task. There could be tasks, in which Bard is (or will be) better than ChatGPT. After all, it is an expressedly experimental conversational AI service.
Things are moving so fast. The competition must be intence.
