I've got to admit that while I thought Bixby Voice would be underwhelming (especially given the info cards that were implemented back in April), I must say it's pretty good. True, it doesn't do everything Google Assistant does, e.g. a simple web search. But it also does things that Google Assistant doesn't. I can tell it to search for a specific contact or group name in WhatsApp, and send a message. I can tell it to open Twitter or Instagram and tweet/post the latest photo with a specific message in the text. These are things that neither Assistant nor Bixby's predecessor S-Voice can do. Heck, even my wife's iPhone can't do that with Siri!
It's not perfect, and yes the voice recognition is buggy. For example I hate the fact that when I say "period" it writes out the word p-e-r-i-o-d instead of inserting a . into the text. And yes, it's a mark of gross incompetence that Samsung has delayed the release of the final version of Bixby twice. We can all agree that Samsung's directors and managers are a bunch of hacks who didn't know how to run teams of data scientists and software developers. But the product that said scientists and developers produced isn't half bad. I understand why people here are angry at Bixby and are simply disabling it. However, I for one think it's OK, and is worth testing out more thoroughly.
