I feel them different ( i have tried them as well).
But having them in front of you, wouldn't it be easier to consider them similar or different?
I own 7000MCD which is of almost exact shape. I must say that the general balance of the knife is quite good and I do not find it too handle heavy.
I would suggest to buy a knife with better steel than 7000D. I suppose the reason for buying a Japanese knife is to get one really good one. I am afraid
