Color me intrigued... Always cool to hear from life-long pros. Quite sure most ways are better than the way I do it.
Overall I like his approach. He has some very good ideas and techniques.
After watching his door setting video I noticed he pulls the hinge leaf off the jamb and install a deck screw underneath. Great idea but worthless. The top hinge takes most of the load. Top two on a 7 or 8' door. The screws holding the hinge to the jamb are short and aren't into very much wood. They tend to loosen up over time, and his method does nothing to hold the hinge tight.
I always get longer screws in a finish to match the hinges and pull one or two of the hinge screws and install the longer ones directly into the framing. The hinge cannot possible work loose over time. My technique has worked very well over the years and I have had the pleasure of setting some big heavy doors.
I have gone back and forth a few times whether or not to shim directly behind the hinge, or use the long screws as a future "adjustment" should things get whacky over time. Without shims directly behind the hinge I could then tweak the hinge location a smidge without really effecting the jamb/casing reveal much.
Fortunately I have not had to go back to jobs to tweak shit like that. I only visit my old clients for a cup of coffee or a beer on occasion.
I started to watch his vid on shop built stairs. I stopped it when he not he'd the nosings of the treads.... But honestly I don't watch any stair building vids at all. I have way too many opinions on the proper way to be able to sit through any of them, despite my admiration for the content creator.
Similarly I could hardly watch his curved trim video.
He does very well for a trim carpenter, but that is more millwright work and has a totally different skill set.
I started my own drinking game. Every time he called a liner(or jack, or trimmer) a cripple I took a shot. Passed out halfway through.
And don't get my started on his stain grain work.....with poplar....much less finger jointed poplar.
He is basically a tract home trimmer. Granted they are higher end tract homes, but still.
But he does quite well it seems, he is certainly quick, and his workmanship is technically sound. The mere fact that he clamps and glues his casing miters earns my respect.
