Is there any advantage to using OTP parts instead of flash?

I looked at prices, and the PIC16F874 is $5.03 at 1000
quanity at DIgi-Key, and the PIC1674B is $5.09 at the
same quanity!

Same with the PIC16F84 series.

Now if they only made "popcorn" chips like the PIC12C509
in a flash version for the same cost as the OTP parts.
I'd love teh ability to be able to reprogram these guys
and not spend $12 for a windowed version.
