IMO, rare wagyu is just not very appealling at all. The flavor is incredible, but the chewy texture is just too much for me. Then again, I have never eaten large pieces, I think the biggest single piece I ever had was 3 oz, so the chewiness isn't all that terrible.
Got some interesting info from the butcher...
Apparently A5 is the highest grade, but he says it doesn`t really translate to the best quality or best tasting beef. It is more a scale to grade the marble, so A5 would have the most marbling. An A3 steak could actually taste better than A5, as marbling is not everything in a good piece of beef. I guess that explains why I see A4 selling for a higher price than A5 sometimes.
Another thing that was interesting is that different wagyu have different melting points. The wagyu I buy has an extremely low melting point (even room temperature it begins to melt) so rare is the best. On the other hand, he suggested that your A5, while it has a lot of marbling, probably has a high melting point, therefore you have to cook to at least medium to reach the melting point and get best results.
