There is no simple answer to that. It depends on the load on the motor and the torque of the motor relative to the torque needed for moving the load.
I think the only reliable solution is trial and error with the actual application.
I guess the safe solution is to use acceleration unless there is some reason not to.
I have been wondering, but have not got around to testing, if a step-wise acceleration would be sufficient - for example get to 1000 steps/second by first running at 350 and then 700 and then 1000.
Of course you also need to consider whether the application can accept rough treatment.
