Google's services tend to be better on android than on the web. Gmail for instance has multi-account support with a unified inbox. You could get a third party client to do it, but I don't know any really good ones TBH, so getting the android app on desktop/tablets is kinda nice. Photos is also significantly better on android.

Social apps, messaging apps, parking/dedicated payment apps also tend to have miserable web support.
