I'm buying the Pixel 4 XL on Black Friday since it's $200 off. I haven't had an Android phone in a few years so I have a question regarding Gmail integration. Right now I have an iPhone and I'm using an iCloud account tied to Google to use their services. Will I be missing out on any Google functionality by using a third party e-mail with Google instead of just have an actual Gmail account, such as data curation, etc?
