I myself like the company, I have bought some exceptional ornamental plants from them. Very impressive Rose of Sharon plants. And others too. It appears the dwarf haskaps just released are sweeter than Solo and Maxie which they describe as Sweet-Tart.
PW also sells the honeyberries developed in the Czech Republic, as do many nurseries. One they describe as the sweetest, Sugar Mountain Blue.
Everybody is different. I myself put honeyberries above blackberries. Marionberry maybe can compete, but most do not from my very limited experience with honeyberries. I grow over 15 different blackberries, I know them, and I like honeyberries more, much more. Maybe even more than blueberries, they have a much richer taste.
I'm not the best judge though as I love all that fruit you mentioned. I never tried Goji, although I do know many are not good, some are excellent. In China it is a mainstream fruit.Gooseberries rock, and I like serviceberries too!
I have about 20 raspberry cultivars, and I do like them better, but I like finding new and unusual tastes. For example I will always grow the rest of my life, Magnolia berries, they are completely inedible fresh. As a tea, I died and went to heaven. About as good infused in vodka too! I was drinking my magnolia berry infused vodka in pink lemonade, and thinking nobody else in the world probably even has, let alone drinking magnolia berry infused vodka.
