Are there any difference, or just two names for the same thing?

Mangetout are flat broad pods and ime almost always stringy & tough.
Sugar snaps look like ordinary peas but are cooked whole - pod and
all, though they can be podded but if they are very full they can be
quite fiddly to open. I much prefer the sugar snaps. If you prefer
growing fairly short plants read the seed packets, some varieties are
very tall.
