I bought Zenva’s last Humble Bundle and I have really enjoyed it. They do a good job of explaining things, and they get you going with working games. If you are just starting out, their courses are a good place to begin.
Having said that, I will say that they are great programmers, but they do not always know how to use Godot effectively. For example, I’m doing their farming game tutorial right now, and they detect if you’ve hit something by creating their own collision detection, when it would be much easier to use an Area2D. They also have apparently never heard of @onready variables and embed node references everywhere.
Personally, I love learning, and at $25 for 30 courses, this is a really good deal that could keep you learning for months.
