If she liked the Radical, the Meanstreak does everything it did, but better. My guess is that she'd play a similar part of the lane. I cannot think of a new one that would be the same, because they have improved.
Now someone will undoubtedly look only at the "numbers" and disagree, but I've used them all, and to me the Meanstreak beats it hands down. As a second choice the DV8 Diva is a great performer, too.
