linear PSUs can be momentarily overloaded quite a bit. That's what I've heard make them preferable for stepper/servo PSUs. The servo/stepper drive will contain more or less circuits for voltage and/or current control, so it's not that important to have a well-regulated DC-rail for the drive. If you oversize a switching-psu sufficiently that should work also. The output of a switching-psu will usually "float", i.e. it's not tied to ground, so you should probably look at grounding in more detail with a switching-psu. Finally if you plan on doing some sensitive (mV) measurements (e.g. coordinate-measuring-machine or similar) you will find that with a switching-psu you get noise at 10-100kHz, sometimes as a periodic spike, in your measurement leads.
