Read from here to get an idea why most of us are quite sure that torque and resolution will be less than with the old modules. Resolution might be improved again by microstepping, but as brent113 wrote: It’s not anything significant - the new (worse) resolution is still more than enough. On print speed I might disagree with brent113, an increase will come in handy with large objects - although that I must admit that in the end it is not really significant if your print takes 2 or 3 days. With torque I think that with milling the 2.5 factor will be felt.
