Victoria has an attack up ability, which is good for dps. Rita is great for blind runs and maps with a lot of ranged units. If you only have Spica, Bashira, and Victoria, a min cost Rita probably has a place on your team.
Rita's AW passive is 20% dps average, so if your Victoria is still skill 1/5, Rita is probably better. Rainbow fairies are so hard to come by.
