Depends on the climate. Peas don't like hot weather, tomatoes do. Here in the cool, wet, pacific northwest, peas grow like mad, tomatoes need a green house, and peppers are marginal at best. Zucchinis/courgettes can grow like mad, but will get powdery mildew if it's wet. Personally, with peas, I just plant short ones (28" vines) on 1" spacing, do a lot of them, and let them self support in a mass. Then, part way into the summer, I infill a few squash plants amongst the peas. The peas die off, the squash takes over, and everything is happy.
