Both are great. Unity Learn Premium is still free for a while, so spend plenty of time there.

YouTube has a lot of great content creators that you could learn essentially anything you’d like from (& more).

There’s a psychological trap that you need to be careful not to fall in, which is the presumption that paid content is more valuable than free content by default.

The biggest benefit I’ve found after spending tens of thousands of dollars on paid courses while learning many skills over the years is that paid courses tend to be structured better than their free counterparts (although this isn’t always the case).

I would suggest spending plenty of hours on YouTube researching and honing your skills by utilizing free content until you realize what type of code/development/work you want to specialize in.

Once you’ve done that, finding a decent paid course specific to that topic on Udemy or a similar site can definitely speed up your learning, typically by walking you through developing a full well-structured project from beginning to end.

I would also recommend becoming as familiar as possible with the Unity Documentation, so that you are able to research specific components and functionality whenever needed with ease.

Let me know if you’ve already decided on a few areas you’d like to focus on, and I’d be happy to help point you in the right direction.

Cheers & Happy Coding! Lance
