Diploma or Degree?

I was wondering what would be the best option - to opt for a degree or diploma in mental health nursing. They are both three years full time so im not sure which one to choose?

Would getting a degree in mental health be more advantgeous such as a better career options and pay or is a diploma equally as good? Can anyone advise?

I think a degree would be the better option if you want to go higher or branch into different area's
