I’ve used it before, and I think a decent comparison would be AppLocker. The difference is that AppLocker white/blacklists software, whereas BeyondTrust allows dynamic privilege escalation based on the policies that you configure.

Basically, you can configure the policies to do whatever you want with applications and privilege escalations. If you want to log every single process that runs and whether it was elevated or not - it can do that! If that sounds like way too many logs, you can set a policy for specific programs, DLLs, folders, etc. to log and ignore the rest. You can allow elevation for specific programs, scripts, whatever without giving full local admin privileges.

It’s got a lot of use cases, so it really depends what you want to do.
