Always recording is a good practice I think. It's so cheap with video conferencing that you might as well. Even if nobody uses it later, it didn't cost much. And if you get that one presentation that provides stellar value it's a gift that keeps on giving.
I don't really agree that a recording is always better than the slides. Slides are a text medium, and as such can be searched. You can also go through them much, much faster than through a recording (even if you can listen at 2x). If you're just looking for something specific, slides can be much better.
And sometimes you need to get the whole experience. And then the recording is much better.
