For me the biggest problem with video reviews is pacing. When reading I can pause, continue to look at the word, think, process, and then continue. Can't do that with video. I mean you can pause but then you have to back up, play again, etc.. It's a mess for complex material that is difficult to digest. Also words allow you to quickly refer back to a previous paragraph quickly, look at a chart or graph, etc... If it's just presenting benchmarks then yeah, who cares about the format? But in-depth deep dives done by people who actually know what they are talking about are rare these days. Anybody with half a brain can regurgitate the tech info provided by a manufacturer but few people can analyze it, challenge it, and explain it.
