check out the walkera forum.
only thing you have to keep in mind is the availability of parts.so if you don't mind waiting for the postman and like to fiddle/tinker go with the walkera.
if you have not flown a noncoax heli you may want to go with a known good setup that has parts readily available for when you crash,and you will,we all have.
most lhs have blade or honey bee parts,I have yet to see any walkera parts.
