Here we go again
Ray Allen is not better shooter than Curry. Curry can shoot in various ways. His off the dribble shooting is second to none. It's much harder to shoot when you're the pg/main ball handler. Not to mention being 2-3 inches shorter. Ray Allen still shot less than 40% in 12 seasons. Curry never shot less than 42.5% so far.
Ray Allen made more threes than any player in the game, but that doesn't mean he was the best shooter ever. He was great shooter, but his record has a lot to do with his work ethic, health, and his team success than his actual shooting ability (which is still way above average). Just like How Kareem Abdul-Jabbar wasn't the best NBA scorer ever.
