Glad to have you here!
A direct comparison of ORY Kratos to other auth products is not yet available.
We have a stub in the documentation for this here.
Since there is a good amount of changes coming to ORY Kratos in the near time, a direct comparison would require a lot of changes as well over time.
So this is probably something we would tackle when we have reached a release candidate for ORY Kratos (1.0).
Other than that, if ORY Kratos is a good fit for you depends on your use-case.
If you are just looking solve login, this would work well out of the box.
If you want something more complex or exotic, there is plenty of options in the ORY stack itself or possibilites to interface it with other auth products out there.
I recommend you try out the Quickstart and if you have further questions, hop in the chat. There you can directly interact with other developers, who are maybe trying to solve the same issues and the ORY team.
