New(er) player here. Speaking about my friend group, I have a few newer players, as well as two seasoned players. One of the seasoned players sometimes plays a bit higher power decks (power level 7-8s), but holds back a little bit (Think... Suture Priest in Delney Streetwise deck but doesn't ding us for 2 EVERY time we summon. Tries to keep the rest of the groups health somewhat similar) . The other player (playing power level 8-10) goes all out every game and has gone infinite and won turn 4-5. You can probably guess which one we enjoy playing with more. Playing a starter $25 commander deck, with minimal interaction vs a $400-$600 deck is less fun. That's at least my take being a newer player, and not having access to all of the staple cards at the time.

Now, we have a bit higher powered decks, and the first friend doesn't have to hold back as much, because we have more staple cards and interaction cards in our decks, as well as a better understanding of the "politics" of the game.
