exactly. xh2s can sync at 1/125 when in ES mode, and for usual studio situation is absolutely fine

i use xh2s in ES all the time now, even for Flash photography. i always shoot at low iso and the minimal difference measured in dr it's not visible in real situations at all, even when raising blacks or shadows.

advantage are obvious, no vibrations, no wear on mechanical shutter, fully silent.

Yep it takes the mechanical shutter in the XH2S (and most cameras ) between 4 and 8 msecs to scan the entire sensor.  It takes the ES about the same time in the XHS2 - or else it could not sync to flash at 1/125.

ES and MS are both rolling shutters.  On the XH2S I probably would only use the ES. EFC has some advantages - on the other hand the second curtain is limited to how fact it can move across the sensor so in reality is is also a rolling shutter.  It just mitigates shutter shock from the first curtain.

CMOS sensors because of the processing circularity on chip are going to be quite a while to get to a global shutter.  Stacked sensors help the read out speed.  For a true global shutter the only available today is on a CCD sensor camera.
