If it's anything like Siri, I'll pass. Went back to the iOS ecosystem last year after being in Android/Google land for the past decade. I used Google Assistant on a daily basis easily 20-30 times and 99% of the time it got me what I needed. Siri can't even do a 1/10th of the things I used GA for, and that 1/10th that it does, it does so poorly that I don't even bother anymore.
What sort of tasks were you using GA for? I use mine to turn a smart plug on or off, and set a timer when cooking. Nothing else I've ever wanted to do via my Pixel 2 is reliable enough to waste time trying. Sending a WhatsApp while driving is the one thing I keep wanting to do, but it's hopeless.
I use it a lot for media stuff. "Play by ", "Watch on Netflix", etc. My wife is very fond of the combined alarm + YouTube functionality: "Wake me up at 7:00 AM with deep meditation music". My toddler has learned to say "Hey Google watch videos of dump trucks". I use it a bunch for basic productivity stuff too: "What's my agenda for today?" "What's my agenda for tomorrow?" "Check my e-mail".
