I was an Android/Google user for years. Then I also made the switch (completely) to the dark side:
iPhone, iPad, Apple Watch, iMac, Macbook Pro, Mac Mini, Apple TV, Airpods
There's nothing wrong with staying with only one platform or using others. I'm 99% iCloud user but also use Dropbox. Never created an Outlook account as I never felt the need. Now I just have my Gmail address forwarded to my iCloud address.
