I've been learning Google Sheets and associated Scripts over the past few months. It doesn't compete with Excel other than the degree to which I've quickly been able to integrate it with the wider Google Workspace - generally a good experience. However, there is nowhere like MrExcel and the closest equivalent is Stack Overflow who's moderator's and contributors are unbelievably pedantic and unhelpful. I've seen several answers where they merely refer to the documentation - which the OP has already stated they've reviewed. Its maddening.
Please MrExcel can we have a MrSheets as a baby brother?
