Gina:
I like very sweet fruit but also high flavor. My favorites, best first, are nectarines, apricot, pluots, figs, sweet cherry, peach, grapes, blueberry, blackberry, apple, and pear. But it's close at top and bottom. I'd put nectarine to peach in the top tier and grapes to pear in the second tier.
Maybe I can find a few figs that will move them up because individual cultivars have a big influence on my ratings. My best fig so far Strawberry Verte does have a flavor that reminds me of the best nectarine. Growing conditions are critical. It's much much easier to grow a high quality SV than a high quality nectarine. Reason is the fig will dry on the bush whereas the nectarine needs months of critical water management to optimize eating quality. And in case anyone is thinking just dry the nectarine fruit, doesn't work that way. The same cultivar of nectarine can range from superb to bland depending on growing conditions.
Anyone interested in what it takes, IME, to optimize eating quality of stone fruit might like this:
