What is the artistry metric in this case, though? It almost seems like it could mean anything.
If we’re shooting for ‘anything with more considerable complexity or general weirdness than most’, there are some artists who, in my mind at least, straddle both worlds: Radiohead, Bjork, Aphex Twin, Primus, Flying Lotus, and I’m sure there are a lot of others. But from what I can gather, your two metrics are at potential odds with one another fundamentally; is club music ever, by definition, anything similar to the former? They just seem like opposing worlds; and what becomes ‘normal’ to our ears over time is likely to erode our feelings of listening to something alien. Remember when EDM was ‘just noise’?
Another thing to consider is that fads are always changing, and artists of all varieties are moving the needle little by little, even if we don’t like them so much, and their contribution still matters; Deadmau5 and Skrillex added more interesting nuances to the electronic music conversation, and that impact will never be forgotten - even if most of us just think it sounds like cheese now.
I’d also argue that small artists (and developers, for sure) make a contribution as well - if not alone, than as a cluster of creatives who also sway opinions, find new workflows, design new sounds, and often share them with others. Hell, lately I’ve been seeing a shitload of YT videos where old metal guys switch over from Protools to Reaper in order to save time - what a time to be alive, right? They all start out with a sincere apology 
I don’t know what my point is, but the infatuation with commercial success as a metric like this is just ludicrous to me. Even the fans of what could be considered generic pop by a lot of us are totally listening to underground artists when their friends aren’t around (you know, ‘quiet time’). The dispersion just doesn’t skew well for smaller artists, because that’s like 99.999999999% of all artists on the planet fighting over scraps, and that’s why we all cry about only having X amount of listeners at any given time (oh wait, that’s just me?).
Every artist makes an impact, I will die on that hill. I could also go on a tangent titled “what is success, anyway?”, but that just sounds like a topic for another day
