Most of the stuff shown are much faster to do yourself if you have your hands free and if you don't you have to pray the gods that Siri doesn't fuck up for whatever reason.
Even something as simple as setting the time, Siri will bork it at least 1 in 10 times. I know that for sure, since I worked at a friend's restaurant 2 summers ago and was heavily using Siri's timer to time french fries blanching (many batches for at least 2 hours every day or every 2 days); this dam thing would regularly use wrong time or not understand at all even though it was always the same dam time and the conditions were always similar.
On the other hand, the Google home at my cousin's place operates at my command without mistakes even though he doesn't even have the luxury of knowing my voice.
People who think Siri is good either are delusional or have special godlike skills. But considering how many hilarious "demos" I have gotten from Apple fans friends; I will say it's the former.
I myself use iPhone/Apple Watch/Macs since forever so it's not like I'm free hating. I just goddam suck like too many Apple stuff recently...
