Instagram gets consistently more downloads and happier users than all of Google's products. IE, take a look at the review history on youtube: https://sensortower.com/ios/us/google-inc/app/youtube/544007...

In aggregate, google's apps have more installs -- but many are installs by the same user, that use gmail, google maps, youtube, etc. Also, the value is about the apps, not the companies / engineering teams / brand recognition behind them.

Instagram has actually been historically dropping in our valuation as the growth curve dips down, especially on iOS.
