After my first day with Bard, I would have agreed with you. But since then, I've found that Bard simply has a lot of variance in answer quality. Sometimes it fails for surprisingly simple questions, or hallucinates to an even worse degree than ChatGPT, but other times it gives much better answers than ChatGPT.
On the first day, it felt like 80% of the responses were in the first (fail/hallucinate) category, but over time it feels more like a 50/50 split, which makes it worth running prompts over both ChatGPT and Bard and select the best one. I don't know if the change is because I learnt to prompt it better, or if they improved the models based on all the user chats from the public release - perhaps both.
