These don't have the same blade material, bladeHQ lists the 1277 with 1085 steel, the bk9 is 1095CV. The 1277 has thicker steel, but I know I truck the 1095CV in Becker's personally. Handle shape plays a role too, but that's largely opinion. The 1277 is pointier, so more stabby if you want/need that... The bk9 is nearly $50 more also, so, I believe it's better, and fir that price difference, it should be. I haven't used a 1277 though, so take this with a grain of salt.
