Think he needs to repeat test with glue as well. The only time you'd use pocket hole screws without glue is if you want to take apart, surely!
I wonder if these people actually now make a living from YouTube - must take him ages doing all these contraptions!

Yes, but what would the result be if he were to turn the test piece through 90 degrees? Myself, I don't like pocket hole screws because I had far too many items made up from them fail when being manhandled off the van and into the client's house or manouvered into position - back when I was fitting kitchens for a living. They work well enough in plywood and solid wood but for MDF or MFC they are totally inadequate - glue or no glue.
I use pocket holes in MDF, primarily in conjunction with Dominos. Seems to be fine.

As Gidon says, the pocket joint should have been screwed and glued, for a fairer test IMO.
But as I would have guessed, the good old M&T is still better.

Maybe that's the thing - people demonstrating things on YouTube perhaps aren't actually using them! It's obvious you need glue to get a strong joint - the pocket screws are pulling the joint together to save clamping and offer some mechanical strength too.
I'm not saying they are a great joint - but they can be useful. As an example - I've made some retail furniture for my shop using pocket holes. I use dominoes for alignment as well. But no glue otherwise I wouldn't be able to get them apart or into the shop in the first place!

When I saw the topic headline I was just about to send you a link to Matthias Wendel for his tests on those joints - as there are others apart from this one.. anyhoo - regarding do people make money... some do, IIRC once you get over 100k hits youtube start to pay you a very small royalty and Matthias in particular does because he gets a lot of hits and has quite a number of vids.
As an example "grumpy cat" - that's the white.. well grumpy looking cat, has made his owner a millionaire because of youtube, yes seriously.

This saw bench was assembled using pocket hole screws alone. 3 Reasons, 1 speed, 2 so that I can disassemble to change if required, and 3 so it can be disassembled to remove. It's been there 2 years now and carries my table saw, router/cabinet and all the bits that go with it and my extraction system.
It gets moved around on castors all the time and never flexes or twists. I've never had a regret about how it's constructed.
A note on glue. The bond created on end grain is hardly worth bothering with unless you use epoxy, which isn't practical.

When I used the phrasing I did, I didn't mean people where just showing what a pockethole joint was, but people building actual things where the pockethole was just the means used. Jay Bates uses it a lot in his projects and I've never seen him glue a joint.
From a woodworking video perspective I am always a bit disappointed when someone pulls out the pockethole jigs or dominoes. Sure it works, but I as a viewer enjoy watching traditional joinery a lot more, especially with the clever approach Matthias takes.
I suppose one trouble with pocket hole joinery is that any glue joint will be end grain to long grain whereas mortice and tenon or dominos / biscuits will be long grain to long grain making the joint inherently much stronger.
