I think the first Mack, Ashley Bashioum, played the character well. Initially, she was the young teen living on the streets, etc. and had the toughened exterior. But then when her character adjusted to being wealthy and matured, I think the other actess, Rachel Kimsey, did a great job of playing a college-aged, more softened Mac. Hence, I really liked the second Mack with JT. If I had to pick, I'd rather the 'second' Mack reprise the role.
