I love the jaffle style ones! Doesn't leak out all the sides and you can put heaps of filling in! I did start hating ours when the bread all started to stick, even if you put butter on the outside, so that's when we got a new flat (think they call them "cafe style") one. Toasted sandwiches just aren't really the same... but I think it is a bit more versatile than the plain jaffle one.
