As others have said, and as I think you know already - the trees and when you get the sap from them has much more to do with the taste than how you boil. If anything, you will get a very slightly darker syrup (and stronger flavor) from your batch boil than someone would with a continuous flow pan.

That said, I do want to make one comment on your technique:

It would be more efficient to put fresh sap in your hotter (closer to the chimney) pan. Your objective should not be to have a "warming" pan, but to maintain a good boil at all times in both pans. The best way to do that is to add small amounts of fresh sap to your hotter pan, so that the boil only stops for a few seconds, and then picks right up again. Then when you move boiling sap from that pan to the cooler pan, it keeps a good boil going there.

When I started doing it that way it increased my gallons per hour by almost a third!
