I haven’t tasted Suebelle but I’ve been researching about White Sapote and what varieties to grow. I found this CRFG talk by Tom Addison very helpful
Remember Tom lives in foggy East Bay where he doesn’t get enough heat to ripen tomatoes, so very different from your climate. I did taste Vernon from his tree and once from a grocery store and both tasted great.
I bought a seedling from him grafted with Vernon and Nettie. Few others recommended LeRoy which I may plant as well but I worry if one tree produces more fruit than I need
