This is how I feel about LTT too. There should never be one single location you go to for all your review needs - even if it had every single product in existence in for review.
I’ll look at LTT videos to see people doing dumb shit with tens of thousands of Britannian Monies worth of tech, sometimes there’s some genuinely good “hey, this exists” (see: PowerToys which gave me Spotlight on Windows), and sometimes it triggers a “hey I could use X, I’ll do my own research and collation of reviews”.
If they can get their Labs up and running and their tests being transparent enough that they can be peer reviewed, then Labs will be a tool in the toolbox, not the toolbox itself.
