Is there a reason why those frameworks were suggested?

There are many commercial offerings that greatly outperform open-source automl approaches.

At my job we use Datarobot and its super impressive. There is Azure AutoML, Vertex Bigquery AutoML, ... Other data focused software components have automl solutions as well I believe, like Alteryx, Dataiku, SAS, ...

If you want state of the art in AutoML, I am afraid this is one of the areas where the commercial space is well ahead of the open source space.
