However I welcomed the change as it was Google which was preventing Siri from working outside of north america ("find restaurant near me"; didn't work in the UK until after Apple Maps)
Today the landscape is different. Google Maps is positively littered with ads which makes it in some cases very annoying to use.
Turn-by-turn navigation, if you have carplay is much superior with apple maps.
They have comparably updated maps data.
So, it's a marginally better usability in some cases and equivalent in most.
Google has two advantages: Reviews and more accurate points of interest (if they are businesses).
