As with anything complex, it’ll take more than a few hours of reading/watching to get comfortable with it.

Sure … so was I. But the switch was well worth it.

They’re a _lot_ easier. It might not look that way when you’re reading about all the details, or converting existing code, because then you’re focusing on the rare edge cases. But for the most part when actually coding you can simply ignore ref-counting. Your code becomes more compact and readable, and you’re less likely to make mistakes.
