Dunno, haven't taken it. But it seems the most complete available. You can see the content for the first course here:

https://ocw.mit.edu/courses/mathematics/18-05-introduction-to-probability-and-statistics-spring-2014/

If you want to get into "deep stats" (not sure what that means tbh), it's probably the best place to start.

There's some mroe OCW that's similar here:

https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-041sc-probabilistic-systems-analysis-and-applied-probability-fall-2013/

with regards to the difference between the 2:

How is this class related to 6.041x? The material covered, and the resources (videos, etc.) are largely the same, but homeworks and exams contain revised and new problems.

That's in the FAQ from the first course in the micromasters.

You may not like the dates, but it seems like the highest quality material out there.
