The Odd Couple Female version - deciding which character to play

Hey guys - it's been a looong time since I've been on this forum but I was hoping to see a few familiar faces willing to impart thier wisdom onto me :) I have been offered a role in a local production of The Odd Couple - Female version and have to decide to play either Sylvie or Renee. Has anyone had any experience with these characters and which do you think would be more fun/challenging etc.? Cherres Guys xxRae
