I really never did this question to myself, but if will happens I would start, trivially, looking for who sponsor those review sites.

Usually their revenue is from affiliate links. YouTube channels have ad spots, merch sales etc. There are many shills of course, but some are doing their best to give accurate reviews and don't shy away from bashing manufacturers for their missteps.

Yet widely known (to enthusiasts) problems, like stutters from the OP, are often not mentioned at all.

LinusTechTips doesn't depend on ASUS money in any meaningful way, but still failed to mention stutters in their Zephyrus G16 review. Some might say LTT is not a reviewer, he is an entertainer, but he undeniably thrives to be accurate while doing so.
