I have an iphone and a PC. Not a great combination. I used to have a WindowsPhone and a PC. After a bit of Android dabbling, I ended up with an iphone. There are good reasons for either choice.
Of course, each one of these points you towards an ecosystem. My own current thoughts are maps.
Google Maps, best on Android, you can use with the web and iphone. Assuming you are good with the privacy nightmare that is Google. However, the maps are good.
Apple Maps. Good for your iphone and a Mac. No Windows browser based maps. You can use DuckDuckGo and Apple Maps but lose functions.
Bing Maps. Great for my PC. No mobile option.
If you are sharing directions, then Google is the way to go. No point in planning a trip on Bing. It stays on your home PC.
Mapping feels like an ecosystem tie in. It is.
