Comparing predators of YP, HSB to walleye (WE) in my experience the HSB are easier to catch, HSB readily eat pellets, grow much better and quicker to large sizes in ponds, and HSB are much easier to catch compared to WE. However as Theo mentions WE are much better guests when invited to dinner.
Theo - Thanks for the compliment. I do love the YP as a pond fish.
