Consider the Stealth Retro. Unless the paint is worth the inflated cost to you. I believe the barrel length & sweet spot are identical. If not, it's very close to negligible.
Eastons & DeMarinis will have some very slight differences in areas like grip, weight, feel & sound. You know, Ford vs. Chevy.
If your partial to DeMarini, then stick with what works well for you. Politics which you can't control aren't worth your time. That mentioned, sometimes there can be some performance benefits to change.
On the men's side, Easton has always been the dominate player, give or take a few years to Worth. In fact, I can't remember ever seeing a DeMarini. However, DeMarini is hugely popular for the girls.
Even though this may be taboo at the moment, many superstores such as Scheels, typically have demos that your daughter could take some swings with for comparison.
