Propeller Websites Vs. Direct Click

I've ran multiple tests against direct click and website from Propeller.. and the zones that convert for me always end up being the same in both.

Can anyone explain to me why I would run both of these if the zones that convert are exactly the same?

I've been running mostly 'website' but thinking about switching to 'direct' just to save on my blacklist costs... because why bother spending so much money to filter through all the junk if it's just finding the same zones that are in direct anyway? (Plus apparently direct has some additional zones that aren't available in 'website'... "apparently".

Running a new test this week... took my long-term whitelist/blacklist 'website' campaign and simply switched it over to 'direct' to see if we get the same amount of conversions or more... and see where the CPA ends up at.

Can share the results after a week if anyone is interested. (Last week I tried running both side by side and they seemed to just compete with each other and drive up costs... higher CPA and no additional conversions from day to day.)

Would love to hear feedback from anyone running long term
