You're not alone buddy, I'm a Bixby fan too! The way I see it, Bixby isn't a replacement to Google Assistant, it's a separate tool used to do different things. I use Bixby multiple times a day, and the fact that I can get Samsung Rewards points (= US dollars!) doesn't hurt.
For those of you who hate Bixby: hey, to each his own. I'm pretty sure whatever works for Bixby-blocking on the S8 will work on the Note 8. And conversely, whatever Samsung does to block package disablers can be trivially re-implemented on the S8 via a software update. I think Samsung would be sort of a jerk to do this, and I hope they don't. All I'm saying is that sticking with the S8 and avoiding the Note 8 isn't an effective means of avoiding Bixby.
