I find I prefer channels with people who are not building a YouTube brand as a primary source of income, I also like to keep at least one channel for the major regions of the country to see what differences exist, might come in handy one day. My favorite is probably Debo's fishing overall, but that includes entertainment factor, for educational I think that Bassresource is at the top, I also like to watch Alex Rudd, and Realistic Fishing, the Googan's are an interesting bunch, but I don't really enjoy their content very often, it's as much (or more) about pushing the brand and marketing as any other aspect, and that gets tiresome after so long, there are also only so many times you can watch them flip out over "monster" fish that are lucky to tip 3lb on the scale, I have nothing at all against what they do, wish them all the luck in the world in fact, it's just not for me, other notably enjoyable channels for me include BassGeek, and Marling Baits, on the Fly fishing side of things Mad River Outfitters are fantastic, so is theslideinn, for trout/salmon species Addicted is hard to beat as well. Probably forgetting a few, but that's life in the big city eh?
