I always found him too long winded... But I guess that's youtube these days. The algorithm is based on watch time, so longer videos are better from a content creation perspective - at least to a point. If nobody watches to the end then it's pointless, but I feel like a lot of people who watch Hickok45 are of the older crowd - his style doesn't really appeal to the younger crowd - and I suspect the older crowd is more likely to sit and listen whereas us young folk don't have the attention span for that.
I don't normally watch him unless I'm looking for videos of a specific gun, and I only watch the first 5 minutes or so. Once I've heard his opinion of the gun I don't need to listen to him ramble for another 20 minutes.
