I go with LTT if I want to know if a laptop is good to use or not.
I go with Gamer's Nexus if I want to know if a GPU used the wrong kind of thermal interface for their VRMs and what effect that has on core clocks second by second, backed by rigorous scientific benchmarks producing huge amounts of data, summarized in highly detailed graphs.
On a tangential note, I prefer GN for their understated delivery and heavy use of data and charts. On some channels the emphasis is clearly more on the -tainment part of infotainment. The default tech video is is now produced with the same template: little jokes between presenters, background history, open ended questions, Netflix type camera shots on the couch, post processing, visual effects etc. With GN at least it's easy to FF to see a graph and listen to conclusions. Other channels require me to be emotionally invested in the content and delivey method and it gets very tiring after a while.
