Black Cherry is sweet here for sure.
However, Jaune Flammee is consistently racey. And Green Zebra has a nice zing. I like them both.
In reds, Nepal has a good amount of acid.
I thought Golden Queen was a yellow with some sharpness.
You can also do as the Italians do and pick your maters before they are fully ripe, showing just a bit of a blush, and slice them for a salad. You'll get the zip in there for sure and it contrasts nicely with a few riper red saladettes in the bowl.
