It's not. It's quickly made filler content that is frequently wrong, misleading, or clickbaity. There are channels doing better hands-on videos and channels doing better in-depth tear-downs, reviews, benchmarks, etc. Max Tech, from all the videos I've seen, has somehow managed to thread the needle of doing it all to a mediocre standard.Max Tech is great and highly informative for potential buyers. Their content is also to a high standard when it comes to new hardware. Apple doesn't advertise SSD speeds anywhere, so at least content creators provide that information. For some people, it matters.
I guess their production work (the camerawork, lighting, editing, etc) is decent considering how they churn these things out, but that's where my compliments to them end.
If you enjoy their videos, that's fine, everyone is allowed their personal preferences.
