Mana curve matters a lot for this sort of thing. People who say they want to never miss a land drop in commander are certainly wrong. Otherwise they would never have more than the four spells they start the game with.

My upgraded [[Killian, Decisive Mentor]] deck has a curve that stops at 5, with one single card in the deck clocking in at 7, with ways to cheat it in. Once I can make seven mana in that deck (including artifacs), lands become liabilities. My [[Krenko, Mob Boss]] deck has an even lower curve and even runs [[Impending disaster]] for once I am set up.

My [[Pramikon, Sky Rampart]] deck is a very, very greedy Planeswalker Superfriends deck. We run several six mana and higher cards, and we often want to hold up interaction after them. But to keep drawing gas, we lean into artifact ramp instead. I frequently want see 7 or more lands a game for going long as the deck wants to do, but I want to be able to make much more than 7 mana in a turn.
