Starting to design out my build, looking for critique

[Chrono]

So, if i got that correctly, I want a stepper that has a low inductance rating and a high current rating, correct?

I plan to use a single NEMA 34 for both X-axis screws(2x 1800mm 2020 screws, around 75kg of mass on the gantry) and a single NEMA 34 for the Y axis as well (1300mm, single 1620 screw, around 25kg of mass to move), with a NEMA 23 for the Z-Axis(single 500mm 1610 screw, 15kg). Taking another look with those qualities in mind, I come up with the following choices:

• X-Axis: ST8918M6708-A
• Y-Axis: ACT 34SSM8460EC
  
• Z-Axis: 60BYG401-03
  

Would these be good choices for my system?
