I used to _love_ it, I would check weekly for new things, maybe there was some new shiny (often beautiful) program to do something really well. The experience was on the 'better than passable' side, nobodies favourite interface maybe, but certainly not terrible.
But I actually avoid the App Store these days, both on MacOS and my iPhone. I never really noticed but I just slowly stopped installing new applications from there (unless sent there by a company website in the case of iOS); this was around the time that Apple Music was being foisted down my throat. I'm not sure if there's a correlation there.
I always suspected there were dark patterns at play in the App Store though. Although every program is reviewed, probably only 2% or less of them become popular, and if you are popular, boy, are you popular. the design paradigm is self-fulfilling. ("most popular"/"highest grossing").
