Pink Lady, Snapdragon, Sweetango are all probably closer to alanced compared to Cosmic Crisp. Cosmic Crisp being more tart than Sugarbee, but still definitely more sweet than tart in flavor profile IMO.
Sweetango and Pink Lady are probably what I would consider balanced sweet and tart.
Interesting. Pink Lady is a favorite for me, and Sweetango is great too, but I'd consider Cosmic Crisp very, very close to Pink Lady in overall balance (I do agree Pink Lady is better though). I'm in Canada and Cosmic Crisp is special / protected and seems to always have to come from the States, whereas I can get the others fresher and grown locally, so perhaps that is a factor.
I'm a honeycrisp fanatic (and it's a good balance of sweet/tart for me). This is the first I've heard of Sweetango, I don't think I've seen them in the grocery stores. Will be keeping my eyes peeled.
Unlike many other apple varieties these days, SweeTango are only available in traditional "apple season" (Autumn months through November in the USA). I've long been a fan of HoneyCrisp, so I tried SweeTango, and while it was quite good, I still prefer HoneyCrisp. I had a similar experience with Cosmic Crisp--not as good as HoneyCrisp, but nice for some variety.
