Which had more impact: Mina's "Pick Up the Phone" or Lee Hyori's "Ten Minutes"?

I remember for a limited time in 2002, Mina completely overwhelmed Lee Hyori.
Of course, once the World Cup ended, their subsequent careers weren't even comparable,
but there were even statistics showing that call volumes surged because of Mina's "Pick Up the Phone."
I feel like Mina's current form is better too.
Anyway, they were definitely rivals back then.
