radiator leak: Firestone or Jeep OEM replacement

I noticed that my Jeep has radiator leak, not dripping but just enough to drop the fluid level once a week. I'm leaning toward the Jeep dealership replacing with a OEM replacement, but am also considering Firestone with an OEM style replacement, which may be a NAPA branded radiator. Any experience with Firestone radiators? I may just go with OEM for piece of mind.

thanks,
Bobby
