Hello, I am trying to learn a backend framework besides Node.js. I am not sure what to pick between ASP.NET Core (C#) and Spring Boot (Java). Any advice, any suggestion is highly appreciated. I am planning to build only Web APIs (no desktop applications or something like that). One thing to mention is that I have no experience in Java or C#. I am trying to learn one of those 2 and stick to it.

UPDATE: The project I am trying to build is a SaaS using microservices that supports multi tenancy.
