I found Uncle Roger while watching a chef I follow react to him. I follow him now because he's funny, and does his research before reacting to a video. "Ginger is for poor people."

Since you named a few, I like Chef James (Makinson). He does a lot of reaction videos (commenting on the right/wrong way to do some technique), but also some recipes, and he did a nice series on knives (buying, sharpening, etc). Brian Tsao doesn't do as many cooking videos as I would like, often reacting to others. He does have some good insights, and I like his friend "Frenchie" (chef/owner of a higher-end NY restaurant). I like Guga (not a chef) because he does experiments to see what will work. Joshua Weissman has two channels...the new one is "recipes", and he has posted three or four videos so far that are him telling how to make a particular dish. His other channel is a mix of stuff (I like the "But Better" series). I also like "Auntie Liz" (Michelin star chef Elizabeth Haigh). When we were in London we visited her restaurant Mei Mei (not Michelin star).

I don't follow, but often watch, Vincenzo (Italian chef) when he pops up in my "suggestion" panel. There are a few others.

Jamie Oliveoil has become a favorite punching bag because he is an actual chef, but he butchers ethnic recipes (from fried rice to butter chicken to curry). He even raise the ire of other professional chefs. But he is a good showman.

The days of "Cooking with Jack" (which was horrifying) are over...we have real chefs doing real stuff. No more "Garbage Stew" (I think that's what Jack called one of his dishes).
