My best fruits are nectarines. Best being the Honey series of yellow flesh, low acid. These take on a superb flavor when grown with some water deficit and brix 20-28.
Next the Arctic series white flesh nectarines.
A couple pluots rank very high: Flavor Supreme and Flavor King. I also like Geo Pride, Flavor Grenade, Honey Punch, Flavor Finale, and Flavor Treat. Most of these are dark skin.
A few apricots rank highly: Tomcot, Robada, Orangered, and Golden Sweet.
Emerald Beaut is the only plum that tastes as good as pluots above.
Best Sweet cherries are Selah, Skeena, Sandra Rose, and Bing.
Figs rate next: Strawberry Verte, RDB, and Paradiso
Summer Muscat is a fantastic tasting grape but very hard to grow. Summer Muscat is good and much easier to grow.
Best blueberries are Sweetcrisp and Springhigh.
I've only got one peach, Valley Sweet, that ranks near the nectarines.
All above grown in a greenhouse in west TX at 4500ft elevation.
