Susan has set up her own biz and also has done this at an early age and paid her mums mortgage (lordsuga will love that). She is only 21 and imo a young 21 in some ways, but she has launched her products and gone to many shoes to sell her products.
Helen is polished, cool, calm, collective, highly professional and will cause no problems, she is innovative, she sees every angle (lordsuga will be snoring).
Helen deserves it as she has shown her skills throughout but she's never had her own business and she has only ever worked for other people. that is a huge change to go s/e, and that is why Susan will win.
