Load Testing for a .NET project with AngularJS

I am looking for a good tool for load testing. I have a .NET project with AngularJS framework. One of the scopes is to test the system for the usage of 20000 people at the same time. One of the tools I am thinking about is JMeter but I found an info that: JMeter has drawbacks such as: - No support for HTTPS connection - No support for fetching AJAX traffic - Some limits in report creation

Please, recommend me some tool like JMeter or plugin for JMeter to get rid of those drawbacks. Thank you in advance
