Compare two profiles in Salesforce: Possible Options

Heroku Comparator App

There is a very good heroku app for the same: https://perm-comparator.herokuapp.com/

PROS: Very easy to compare multiple profiles and produce a comparison table.

CONS: Runs on heroku server — Security concern. Also, do not give next level drill down like FLS check, apex classes

GitHub

Being a developer I like this as it gives you full control. But you need git + Workbench expertise

You can have two branch with a file having all metadata of a profile (which can be easily pulled by using workbench). After that pull a request, it would show all differences as conflict.
