Sardonyx. Because Garnet is in both the fusions, you just have to compare Pearl to Amethyst. Amy is more thoughtless and agressive than Pearl, who thinks more logic without exhausting her body too fast. Like the trivia says, Sardonyx does well-thought things with minimun effort, Suglite likes to just smash.

So yes, I would say Sardonyx.
