Payflow is Paypal's gateway solution (formerly verisign) which allows you to use their gateway along with your merchant bank. Payflow Pro is basically the same as website payments pro where they provide both the gateway and merchant bank services. I use Payflow Pro and I would recommend staying with website payments pro if you already have it. Support for the payflow pro payment module is not nearly as good as website payments pro which is bundled into the base zen cart. Just my 2 cents
