Day_Sleeper are you talking about chineese made motors from a new company called "Long motors" ? or logomotors i cant remmeber?
Anyways according to my experience both motors are pretty much alike.. 0.9 motor is has a smaller step (so remmeber to update your firmaware accordingly), with 0.9 you get a better resolution than the 1.8 degree, as the accuracy is higher.
4800 g/cm or 4200 g/cm are pretty much the same.. 4800 is slightly stronger = better as the motor will not put too much effort.
Its very important that you look at the CURReNT rating of the motors aswell or what is called current/phase.
if the current phase is higher than the current that you can supply - then you wont be able to reach that torque.
example: a 4800 g/cm motor with 2A/phase will not reach its 4800 torque! and in that case i would prefer a 4200 g/cm 1 A/phase motor over it! (incase i was using the regular 4988 stepper driver).
Note that the 4988 driver can reach 1Amp only, the new versions can reach UP TO 2A ONLY IF YOU COOL THEM PROPERLY.
Hope this helps!
