I'm not sure Steam reviews are more reliable though (reminds me of the NBA 2K20 review bombing, it was a top game in the 'Horror' category after).
However some good points are, it is required to actually own a game to leave a review on Steam and there are many games on Steam without reviews on Metacritic, but there are many games on gg.deals that are not on Steam, either.
I would suggest both as well or maybe also OpenCritic. Could be individual search filters for each or total average.
Interesting enough in the Steam library you can sort by Metacritic score, but not by Steam reviews.
