I've been using Office 365 for about a year now after moving from G Suite - didn't like how on G Suite I couldn't use certain products like Stadia and my Google account was essentially hostage to the monthly bill.

I did have to go through the process of transferring my data (Photos) manually to a standard consumer Google account and losing some stuff like my Google Maps Local Guides status, Android purchases (I use an iPhone now anyway but not nice to lose the purchases in-case I switch in the future) and my YouTube account (wasn't much stuff on it anyway) and resubscribing to all my favourite YouTubers. Wasn't too painful - disgraceful how Google allow you to transfer your standard Google Account to a Gsuite one but not the reverse.

Been a rather pleasant experience on the Microsoft side. Integration into the Outlook smartphone apps and Windows 10/11 mail client is second to none and the webapp is solid too. The spam filtering is excellent too.

Quite nice how if you login to Microsoft services and have the same email address for your standard Microsoft account and O365 you can get the option to select which one when logging in.

You can find resellers selling keys for a year of it, I bought mine from Amazon. Will definitely be renewing this year.
