I'm all about understanding the concept of a technique to better understand the success behind it. Everyone's swings are different but the concept of a good strike on a ball is universal. Face hits ball, ball flies! How you deliver it, well that's on you. How you get from A to B depends on how you play, but sometimes understanding what the end looks like and working backwards for your own tendencies and understanding what they are trying to show, is so much better than "learn this technique to stop slicing". Sure, you catch a nugget every now and then (towel drill comes to mind for that back elbow staying tight) but again, it's a concept and reinforcement.
I'll watch a few YouTuber's, but not for the instructional content usually. I prefer the course vlogs. Watching the mental approach and how some of these golfers get around the course, that's half the game. None of them are perfect golfers. They make mistakes (I know, editing is editing) and show how they recover from those mistakes. Matt Fryer has put out a few videos of just mental approach before shots, where should the focus be, etc. He's also done a few conceptual basic (ball in front of stance, chips go higher vs ball in back of stance, chips stay lower and run out) things that if you actually think about it from a logical standpoint, it makes sense. Sometimes, all we need is someone to say it for that little light bulb to turn on!
