For me it depends on how the information is presented. I like it in a concise manner, and something that gets straight to the point. So it really depends on those factors and if the article or video meets them or not.
I'd love to do both. Learning for me works well when I have all three mediums; audio, visual, reading. It's always nice when you stumble across an article that has a video and a video that provides further reading.
(Shameless plug - It's also why my company is launching our tool on Product Hunt on the 7th of November called Vidiofy that helps publishers convert articles into videos)
