I'm going to disagree with all of the comments here so far, and say that if you're looking to learn ASP.NET with the aim of using it at work, you should stick with ASP.NET MVC. If you're learning for the fun of it, it really doesn't matter, but 99% of work being done in ASP.NET is on the existing .NET stack (MVC/WebForms). It's not a corporate thing, or an enterprise thing. We use .NET because it's a mature platform, and ASP.NET MVC works. I work in an agency on MVC builds, and I doubt we'll be using .NET Core for at least a few years.
