So 'loads of people' might not be that 'loaded'.
The assistants you mentioned have far better external applications than Bixby and Cortana is on the way out. I think of Bixby as more of an assistant to handle phone features, ie. adjusting volume, reminders, etc. Use Bixby for doing things on the phone and Google Assistant for everything else.
