Well, she's a nice combination of both breeds. I would say her leg color and body shape favor the Barred Rock, but she's definitely bearded, like an EE. Her comb looks to be a combination of the two breeds.
I also have a mutt EE roo, with a "comination" comb kind like that. Not sure if he carries enough of the blue egg gene to throw green layers, but I'm thinking about breeding him just to see what his daughters might lay! (well, it's an excuse to hatch more eggs, right??) He's supposedly 1/4 Americana the rest Buff Orpington, and his sister laid green eggs so there's a chance. hehehehe
I love my Barred EEs, which are all BR rooster over blue Ameraucana hen. Riley and Panda are half sisters, both have the same mother, my Charlotte, but their sires are brothers, Zane and Dutch. Both lay green eggs, Panda's is dirty olive and Riley's is sort of a bluish green.
I personally like that BR/Ameraucana cross. Both mine have pea/single combo combs. Your girl has a nice beard, Maxx.
