Those lectures were the very best I had at uni. Because they were meant to be copied it allowed for two important effects: you process things very differently when writing with you hand, and just copying rather than transliteration from a slide say means you can focus on what is said and what's going on with the math.

For me this meant I recalled it way better. I hardly looked at the notes afterwards, but writing them down were crucial. I also could follow the process and ask questions where I didn't understand a step. When I did review the notes, they were very well structured and thus very informative.

The absolute worst lectures I had were slide-based. I either had to focus on transliteration to notes, but that meant I had to focus on that rather than what the professor was saying. And if I did the opposite I didn't write notes and thus could hardly recall the details if at all.
