This is of interest to me as I am on the cold edge of zone 7. Knowing that hardiness was a challenge I planted Celeste and Hardy Chicago plus a number of others.
As it turns out, I do not at all like the flavor, the size or the productivity of either Celeste or HC. Kadota tastes to me much like cardboard. Herman's MVS is tasty but small. Sal's fig is no better than Celeste in my opinion, small and of mediocre quality.
On the other hand, I have a Texas Everbearing (what CAN it be?), a Bayernfeige Violetta and two local unknowns that make large figs and are delicious. A Joe Morle Paradiso in the ground is making large figs that are very tasty as well.
Of course my two unknows (very much unlike in leaf but similar in size and color) have survived in Tulsa because they were either very hardy or in warm microclimates. Who knows until I put them in the ground here?
Unless you are principally a collector without an interest in what you get for your efforts, productivity, taste and the rewards of labor count. I'd certainly like to find that ideal fig, highly productive, large, cold-hardy and flavorful.
