I prefer Sugar Snap peas to either mange tout or podding peas (because I'm the one who has to do the podding) With SS, you get the best of both worlds - no podding but the peas are crispy and sweet - you eat them when the peas have grown inside, but with the pod still on. They are even more difficult to tell from podding peas than MT.
Our podding peas are only just ready. I grow them for eating straight off the vine - it makes the grandchildren think they're doing something bad, whilst getting some lovely fresh veg. Any left get mixed with SS peas for dinner, or might get frozen.
I don't think it's as easy as you portray to grow good peas P'Vet. Here if we sow them direct into the ground, indoors as well as outdoors, they will either be robbed by the birds or eaten by mice in the early stages. They can get moulds and mildews in unfavourable weather, or just curl up and die for no apparent reason.
