Hurricane King 3 vs H301

I hope everybody is having a pleasant day. I had a question about these 2 blades. I know tons of people who have played with h301 and say it is linear, near all wood, and has almost no shortcomings. However I haven't met any who have played with hking 3. I believe the only difference is in the type of composite fiber that is used, but could someone provide a comprehensive comparison of these 2 blades? Is hking 3 similar to long 5?  Is it head heavy or balanced? Is it a well suited blade for backhand? I know one of my rubbers will be a blue sponge h3 neo, but the other I have no idea. 

P.S if you like to provide some info about nittaku septear, more than appreciated, but the focus is the comparison of these 2 guys. 

Thank you in advance for your responses .
