I've grown or tasted a lot of blueberry varieties mostly SHB but some NHB. My two favorites by far are Sweetcrisp and Springhigh.
Sweetcrisp name says it all. I've tested them at 18 brix which for a blueberry is very high. 10-13 is more common. Think highest I've measured on anything else is 14. But haven't measured that much because it's so hard to get enough juice. That said the outstanding characteristic of SC is the texture. When you try them you'll know what I mean. Downsides are modest yield, need for pollination, and wild hard to train bush. But the fruit is worth all the effort.
Springhigh isn't firm but has the best flavor of any I've tried by a good margin. Berries are big, easy to pick, and good, not great, yield. Emerald yields way more than SH but to my taste isn't anywhere nearly as good flavor and it needs pollination. The bush of SH is upright and very easy to train. Plant is also self fertile no need for bees and another variety. This would be a very good variety for a first time grower only wanting one plant.
Both were available at Just Fruits and Exotics and FHN yesterday. Maybe FHN has learned their leason otherwise might want to stick to JF&E.
