My answer will probably always be the cayenne. Really enjoy a lot of the new peppers I am growing this year, and a lot of the ones I have grown for many years, but I have to go cayenne. Can't help it, I am a creole kind of guy.

I actually agree with Silver Surfer! Their flavor is exceptional and useful in so many ways, Outside of that, Orange Thai probably as I use them endlessly.

Maybe you should try a hotter cultivar such as the Biker Billy Jalapeno. I have not tried them but other people have said they were hotter than a Cayenne.
They do have a substantially hotter kick than your average jalapeno. make your eyes sweat heat
