For some questions I asked, I liked Bards response, for some others I liked ChatGPT. Moreover, Bard is much newer vs ChatGPT had a lot of fine-tuning data from being used for a while now.
The "best" will change over time, and will depend on ease of use, speed, availability, how close they are, rather than just the "best response" to more types of questions.
A Chat app that is good enough, but with better integrations, enterprise support will be used by enterprises. Just like why Meet and Teams gained userbase over Zoom, even though they came in the game late.
I can imagine some kind of multipoint benchmarking in the near future. What do you think?
