Phil and Stacy create repeating patterns using shapes. Phil's rule is "oval, square," and Stacy's rule is "oval, square, circle, oval." If they both have 96 shapes in their pattern, which pattern has more ovals?

Phil's pattern has 48 ovals because 96 / 2 = <<96/2=48>>48

Stacy's pattern has 72 ovals because 96 / (1+ 1+ 1 + 1) = <<96/(1+1+1+1)=72>>72
Stacy's pattern has more ovals because 72 > 48. Answer: \boxed{\text{Stacy's}}.
