That's a pretty good article, although a little too enthusiastic for me.
I was "all in" with Google back when I was using Android. Music, photos and drive. Part of my move to iOS was to see the procedure, for me, from Google to Apple. I got all my files from Drive to iCloud, pictured from Google to iCloud, and from Music to iTunes. I still have and use my Gmail address (because I've had it since before Android existed) but currently have it forwarded to my iCloud account.
While I don't currently have either Google Home or Apple HomePod, Siri on my iPhone and iPad work just fine for me and both my wife and I have Echo and Echo Dot, again both work just fine for what we use them for. Our house is old and no automation is set up. Not really sure I'd use it even if I had it.
So do I think one ecosystem is better than the other? No. Both both have different features and fit different people and lifestyles.
