The Voodoo seems like it is a better bike more travel but most importantly an air fork which is the most crucial part. Plus I think Voodoo is a cooler company overall but Giant really doesn't do anything for me. If you are getting this CycleScheme you might also consider a slightly upgraded budget as well since they are taking care of some of it but if stuck where you are skip anything with coils (unless a very high end coil fork which is rare spec on a stock bike).
