I used to grow only snow pea pods, but then tried snap pea pods. I have yet to stir fry any. They are so sweet and juicy that they seldom make it all the way into the house. I would pick a double handful and eat them all while driving to work.
I often let the (flat, thin) snow pea pods grow until they plump up and have visible fat peas. They are a little less sweet and less tender that way, but have a much greater yield since each pod is plump.
I like snap pea pods better, since they are "designed" to be sweet and tender at the stage I like the pods (big and fat). But even they get starchy and tougher when TOO big.
I like pole pea pods better than bush: I get more peas, I bend over less to harvest, and I have to provide strings to bush peas anyway, or they sag onto the soil.
I didn't taste much difference between 'Sugar Snap' and 'Super Sugar Snap', but 'Super Sugar Snap' yielded more and was a few days earlier. Both are vine types with 5' - 6' vines. 'Super Sugar Snap' is my current favorite.
Here are some other snap or snow peas I'm going to test eventually:
pole snap/snow pea "mangiatutto"
'Carouby de Maussane'
also called:
Pisello Rampicante Gigante Svizzero
(I tried these several times but got low germination in cold wet clayey soil. "Pick when the peas have just started to swell for best taste".)
bush snap pea:
'Cascadia'
'Sugar Ann' ("Extra early compared to other snap peas. 1984 AAS winner. Sprout on paper towels to prevent rotting.")
My favorite snow pea pod so far is unfortunately a bush variety:
'Oregon Sugar Pod II '. It stays pretty sweet and tender while the pods get very big.
I also plan to try :
'Rembrandt' snow pea pods with 4' vines
and
'Avalanche' bush snow pea pods "Semi-leafless, many tendrils for garnishes (semi-afila type)"
