The first variant energises one coil at a time. The second energises two. The second should have better torque as there is no risk of zero excitation at any point in the sequence.
But... I don't think the second one is right. I think it should be
1010
0110
0101
0011
1010
1001
0101
1100
Which is a half-stepping 2-coil sequence.
if you are building your own driver then just let LinuxCNC do the heavy lifting. It can output arbitrary patterns (in table mode) so you can experiment for free. Don't put your assumptions in hardware
