I am completely in love with the Zapotec Jalapeños. Hands-down, my favorite. Only possible "criticism" is that they are hotter than a lot of other Jalapeños, so they can be hard on the folks you give them away to. But yeah, they are the total package, as far as Jalapeños go, in my opinion. Decent sized, like a medium-plus on average, with meaty walls, juicy sensations, intense flavor, beautiful corking, and they're just so dang uniform...each one is very much like the others, which wasn't true for the other Jalapeños I grew this year. I'll likely grow a bunch of Zapos again next year, and maybe a few plants of a new "challenger" in the Jalapeño category.... but maybe not. As of right now, it's tough to even imagine a better Jalapeño.
I know a lot of ppl are wild about Fresnos, but I don't get it. I mean, I like to see them at the grocery b/c they are often sold ripe, whereas Jalapeños tend to be sold green.... and grocery Jalapeños tend to suck. So, yeah, i'm glad that Fresnos are an option at the Mercado de los Gringos so often, but I still can't imagine growing them in my garden.
