I have a mixed Google/Apple smart home environment. I don't know how fast Nest was before, but I find it slow-but-not-unusable nowadays, still useful enough that I wish Apple would introduce a HomePod with a screen. That said, I also wish Google would finally kill Nest and just go forward with Google Home, since it's a pain to have to remember which one configures some of my devices and which does the rest. Apple needs hardware partners to more deeply invest in HomeKit, particularly in the camera space. It's coming along but still feels behind. A compatible camera (or one bridged to HomeKit) will show up on the AppleTV pretty quickly. The official HomeKit devices I have work consistently and well, and the ones I bridge in with HomeBridge work most of the time without intervention. It is super cool to ask Siri to open the garage door when I'm walking the dog and it's cold out. I would say it's viable, if not improving all the time.
