mehliss has a better skill IMO , but in terms of dps , both cyrus and barba blow her away , for the single reason that most of the times u will use mages , is when there are many clustered enemies. Doing 500 damage to 8 enemies instead of 4 can mean quite a lot. That being said , their damage drops a lot when there aren't many clustered enemies. Still they both have higher base stats , so it's generally a toss between them . depending on what you preffer
