If you're happy with the commercial offerings there isn't a very compelling reason to use local models. The local ones are not "better" in general. But sometimes people have reasons to use local models, eg. privacy, customization, control, etc. I personally use it mostly to keep tabs on the latest models released on huggingface. There has been a lot of interesting developments since last year, and models have become more and more powerful.
