A real question about EEPROM vs. Flash

So, I'm bidding this ultra-sweet project, and I'm studying the
data *** of the PIC18F6520/8520/6620/8620/6720/8720, and it
says, Flash: 100,000 cycles, EEPROM: 1,000,000 cycles. What
are the other differences? Is flash cheaper than EEPROM? I
have noticed that it tends to get used for program memory,
and EEPROM for data, but are there any other differences,
like, maybe program/cycle time, erase modes, that sort of
thing?

Thanks,
Rich
