To answer the question I loved both girls and both were brilliant housemates, from Gina accusing people of racism to hazel stealing that girls man and reducing her to tears, both contributed a lot to the season.
It gave be so much joy when their feud began(that mirror scene will forever be iconic
).
But overall I would say I prefer Gina as she had the comical factor to her cattiness, she honestly was so funny I don't know why people took everything so serious.
