I personally think that what's more important is the "readability" and cleanliness of one's writing.
Most if not all Engineering graduates do not write in cursive and write more in a big readable straight line character(like a times new roman font). This is mostly for readability purposes as it is important that other people who read their writing do not make any mistakes.
Cursives on the other hand add sophistication. It also adds grace and even liveliness to the one reading it. Learning to write in one would be good if you are dealing mostly with people.
