There are several ways to compare activity between different accounts.

Comparing Multiple Accounts in a Network

If you have multiple accounts in a social network, you can use channel reporting to compare activity and toggle between the accounts. Go to Channel > Select the network > Under Activity Timeline, click to unselect the account you want to remove:
