Kagekiyo W1 vs B1

[instantramen]

Anyone have experience with kagekiyo's white 1 vs blue 1? I currently have a kagekiyo B1 suji, maybe thinking of getting it a B1 brother gyuto, but am curious about how the W1 gyuto compares in terms of edge retention, hardness, etc on these particular knives. Also open to hearing about how W2 stacks up to the others in terms of overall value despite being a more budget friendly line.

For context, I have a maboroshi on the bst that's the only W1 knife I've used, so comparisons between the kagekiyo W1 and TF's W1 would be helpful for me!
