for 25mm/s (1500mm/min) you need to spin those motors at 300rpm. At 72v those motors have a corner speed of 1023rpm so you will be near optimal as regard their torque curve, indeed you might be better off with 1:1 gearing (motors running at 600rpm). Assuming a 20mm screw then you should get pretty close to your goal.
The 3.5Nm motors have a higher inductance and are more marginal than the 3Nm ones at the speed you require with 1:1 gearing... stick with the 3Nm
