I think he makes a few worthwhile points, especially if he's catering for people new to recording, DAWs and audio production.
He's right - simply switching from one DAW to another won't suddenly improve your output any more than swapping from MS Word to Apple Pages will suddenly turn you into a great novelist. He's also right that it's possible to produce good sounding results on pretty much any DAW. What I think he misses are a couple or three things.
The first is that different people mentally "see" things differently. What makes absolutely clear, obvious sense to one person doesn't necessarily to others, and switching from a DAW you find really unintuitive to one you feel at home with can make life much easier. But I don't think someone's at the stage they can make that kind of decision until they at least have a grasp of their original DAW so they know what they don't like about it.
Secondly, some things depend on what kind of music you make or record. If you do a lot of work with MIDI then a DAW that is good with MIDI and well-featured is going to do a better job than one that isn't so capable. And sometimes it's the quirky stuff unique to a particular DAW that influences the decision.
If you want what Ableton Live does and you haven't got Live then switching to it makes perfect sense. If you use MIDI a lot some DAWs are better at it than others. If you need a score editor because that's how you think or you need to print sheet music off then again, some DAWs will suit you more than others. But first of all, you need to know why you have a problem with the DAW you have and what the alternative offers.
And so on. There can be good reasons for changing DAWs - like avoiding Win10 >:-) - and if nothing else trying different ones can be an interesting learning experience in itself. But changing because you imagine one will be easier to learn or use is a gamble.
I'd also add that going crazy with accumulating hundreds of different plugins won't necessarily improve your mixes either. Until the principles of eq and compression make sense simply changing from one eq or compressor plugin to another isn't going to sort out your eq or compression issues. And I say that as someone who has far more plugins than he really needs, some or which I use a lot and others I hardly ever use. But I like to think - or maybe pretend - that I do know why I have those particular plugins.
Overdrive and fuzz pedals on the other hand, well, after 40 years electric guitar playing I just keep buying the things in the hope that somewhere out there is the magic one that will produce the exact sound in my head. Every time I step on it, without fail. :-)
