The worse the system the better it is for the newbie GM. Because it's already fucked up, so there's no standards. They can't make it worse. They can at most make it better by forgetting or tossing half the rules of a bloated system. Then they are evaluating what's actually needed, what works and what doesn't, which results in much better system.

Compare that to a GM with a rigid and well known and relatively simple system, or just fucking 5e or something. There's expectations. There's more pressure to keep to the rules for a newbie who doesn't know to trust their judgement over the rulebook. So their story might hit a snag with a rule they didn't know. Their encounter might fall the pieces. A single overlooked thing could kill their plans and they wouldn't know to homebrew/hourserule it away. They'd be putting the rules over themselves.

So play the worst fucking game you can find and break it in like a pair of boots. If no one else knows how it's meant to be played they can't argue.
