Maybe I should not have been so "absolutist"...;-)
There are differences between EIS on/off and OIS,
but they are usually much more subtle than particular
implementations of OIS or EIS. For instance, the
worst OIS I have seen (with zoom at the long end) is
on the VX-2000/PD150 - I cannot hand-hold this camera
without vibration and shake in the picture (with zoom
at the long end), though this is rather easily done
with the VX-1000; the XL-1 OIS stabilizer is good at
stabilization, but has a tendency to "swim"; etc.
The EIS stabilizer on the EZ30U is totally unusable;
the EIS on the PC-1 and TRV-9 Sonys is great in
bright light, with only minor negative characteristics...
In other words, it is hard to say that EIS is
better/worse than OIS overall in bright light - as
with most things, they are "about equal, but
different"...;-)
