I don't think Ronnie has any more natural talent than Efren, not even 1%.
Neither do you according to your post ^^.
If Efren was on Snooker since age 8, and you would pick Efren, the you believe Efren has more natural talent, as do I.
People from across the pond, don't inherently have straighter strokes than pool players, but they do have straighter more pure strokes because their game demands it.
Look at the fundamentals drilled into Ronnie's game since a child, and realize the gifts that were GIVIN to him.
Now look at Efren, he had NOTHING, and turned it into something unbelievable.
Look at it realistically and tell me who achieved more.
Efren looks down on the entire world when we're talking "Natural Talent", it's not even close.
Efren came out of the dirt, Ronnie came off a assembly line in a factory.
