All three of that selection are good, but red raspberry gets the nod, although commercial versions can be a bit on the watery side. Followed by purple raspberry, yellow raspberry, and blackberry in no particular order. I haven’t had a dewberry in decades, so it’s hard to rank. Black raspberries are pretty good, too, particularly when they’re big and plump.
There are some other bramble berries that probably should be considered, too. How about loganberries and boysenberries?
We live just down the road from a large berry farm. Both loganberries and boysenberries are raspberry-blackberry hybrids. Loganberries favor the raspberry in flavor, boysenberries favor the blackberry. We make jam out of a blend of the 2. Awesome stuff. I agree on the marionberry, but that berry farm, for some unknown reason, took them out in favor of more blackberries.
