Well since I posted this question I have scoured numerous forums checking out the differences. I have come to the conclusion that this is completely an opinionated topic. Each time I came across the subject it would be threads of pages of post each picking a side, some even saying that they fly their friends opposite set up and see no difference in response between the two and found some post that a pro flyer prefered the mechanical setup.
Needless to say Im not swayed eitehr way right now since I havent flown a T-rex yet, I'm just building one to get a more stable machine. Budget doesnt seem to be a problem since the hardware price and requirements are the same. HDE I think would be the better option at first just for the gained experience and but the market seems flooded with CDE versions.
Not sure which way I'll go yet, but thanks for replying.
