If you like Yod Fah, Purple Hon Tsai Tai is also one of my favorites and it has beautiful purple stems.
My favorite mustard green is Ho-Mi-Z, mature leaves are beautiful with dark purple and green and it's the best tasting that I have tried. It's spicy but also has a sweet aftertaste. One year when I was cutting back the large flowering stalks, I noticed the inside of the stalk looked tender so peeled the outer layer and found it to be one of the best tasting vegetables for stir fry and also good raw.
Best tasting collard green is an heirloom variety from North Carolina named Yellow Cabbage Collard. Cascade Glaze collard is a unique collard green with shiny waxy coating.
My top heat tolerant lettuces: Italienischer, Cougar Batavian, and 2 Frank Morten varieties, Jester and Icy Oak.
With all my lettuce trials I found that I prefer growing open head lettuces that I can harvest from over a long season. Some of the heading lettuce tasted good but it was hard to control slugs hiding inside and all that time to harvest one head wasn't worth it for me in my small home garden. With the open head lettuce varieties, instead of just harvesting the outer leaves for salad, I harvest from the young center leaves. As the plant matures the center leaves continue to have crisp texture and good taste even when the leaves are small and the larger outer leaves keep feeding the plant. I also found when the lettuce starts to go to seed they will grow several feet tall and the leaves can still be harvested as good cooking greens. They are excellent green for soups and stews. A can harvest for several months from a single lettuce plant.
Sea kale, Crambe maritima, make gourmet greens easier than belgian endive. This is effortless to grow. I grow them in pots, they go dormant in winter. Before spring growth I cover the top of the pot with a black fabric pot to exclude light. The new growth is tender white with beautiful pinkish purple leaves. Makes a fine dining restaurant quality salad. The leaves during the regular season that get sunlight can be used as a cooking green.
I also have greens that are my own breeding selections that I've worked on for around 15 years from crosses of my favorite brassicas.

Wonderful information! I am hoping to grow Piracicaba Broccoli next year. I would like to cross it with the Gai Lan to create a seed savers B. Oleracea for Florida. I am growing Old Tokyo Komatsuna and Toy Choy Pak Choy. I hope to make a cross between the two that will keep the eating quality of the Toy Choy without bolting so quickly. I am on my F2 generation of a lettuce hybrid between Queensland (a heat tolerant open head cos type) and Red Romaine. I am calling it Sunkiss. Everyone tells me that the flavor is excellent. I plan to select for the red/bronze color now.
I wonder how a "tree okra" would do grafted onto Bele. I have grafted okra to Cranberry Hibiscus several time with ease, but the Clemson Spineless that I was growing seems to die out after it fruits a couple times. I was hoping that grafting would solve that, but it did not. I think I need a longer lived variety like Nkruma Tenten.
