This video is quite old, and while I have always been an Office chair > Gaming chair guy, and a lot of things in that video are still true I have a Secret lab Titan Evo, i.e. a gaming chair, even though I despise the aesthetics of it. When I was looking to get a new chair my options were very limited, I had essentially ruled out every other option one way or another and was about to buy an Autonomous ergo chair when a friend of mine did, so I tried the chair at their place, and it sucked. And it sucked in a very specific thing, the cushion was too soft, it felt like almost no cushion at all, and I understood exactly why no reviewer mentioned it, being tall and fat meant I weighed quite substantially more than any of them.

With my last option for an office chair gone I had to look elsewhere. I had never even considered looking into gaming chairs because I know they're all cheap uncomfortable things, but in my research for a chair I found lots of people saying the Secret lab was different, so I started to look at a lot of reviews about it and the consensus was that it was the best gaming chair, even some channels that exclusively review chairs were commenting on how good it was (for a gaming chair), and there was one comment that lots of them did that made me pull the trigger, i.e. "the seat is hard, but not in an unpleasant way, it's kind of like a car seat". I'm used to driving for multiple days at a time, so I know a car seat was better than my current chair and better than any of the office chairs I've tried.

I ended up buying an XL model, and indeed the seat was too hard, but with time I grew used to it, and I also read lots of articles explaining that harder seats are better for the back. I've been using it for a couple of years and the pain I had in my back from sitting on a cheap amazon chair is long gone, I now consider it one of the best chairs I've ever sat in for long periods (which includes a Herman Miller I had at my previous job). Is it the best chair in the world? No, it lacks several adjustments that I had in old chairs that I miss. Is it for everyone? Probably no, if you're not heavy enough I don't think the cushion will feel comfortable even on the long run, and I consider it to be the most comfortable while reclining which is something I do periodically to take the weight off my lower back, so if you don't do this it might not be great. However at that price point it's competitors are cheap office chairs that also lack features or have shitty materials, or good used chairs, and the used market is very specific and might not have what you need when you need it.

So all of this rant is essentially to say that, yes in general Office > Gaming, but there are exceptions and I think that while their conclusions will be very similar they should do another run at it with the Secret lab as a competitor.
