For my money, it's Allen. Lamar is a terrific runner but QB, not so much IMHO. There's something missing there. And I don't believe he's ever had a great receiving corp. Great D & ST, great run game. Questionable receiving corp.
Allen is a QB who seems to have the ability to will his team to win......unless it's vs Mahomes, who does that better with the Chiefs.
Goff has been to a SB and winning one wouldn't be like getting a monkey off his back nearly as much as getting a monkey off the Lions' back.
Burrow plays for a tight assed owner and shitty franchise so his winning one would be a Super-accomplushment. Pressure to win it shouldn't even enter the conversation.
There us something to be said about Prescott not being part if this discussion. He's the highest paid playing for the most valuable NFL franchise. So what if he's nowhere near as talented as the other 4. Everything points to YOU ARE EXPECTED TO WIN IT
