I'm not sure "plain" is a bad thing as its subjective. What i like about Wild Eagle vs. Swarm, X-flight and Raptor is that WE's layout is built for speed with lots of up and downs (my favorite thing!) and a few inversions, wheras the other three are more compact, with lots of speed-killing turns and a few inversions. I think WE will be more of an air-time monster than the others appear to be.
It's in the process of being built, as are two of the other three, it is too soon to form a real opinion about it.
