Surely an orthoscopic eyepiece gives much better sharpness on axis
than the Erfle-like Orion Expanse oculars (I have the whole set.) So
like many other planet enthusiasts who prefer orthos, I'd agree with
this strongly! Plossls are almost as good.

Then try to view over a body of water, (sea/lake etc) it may give much
steadier seeing.

This I have tried innumerable times here, and have always had worse
results than at high elevations at locales with stable, laminar
airflow. I cannot remember one single time when I was near a body of
water where the double star and planet observing was not badly
hindered. Perhaps, though, being several miles *inland* from the
ocean, at a high elevation, I get best results. But not at any of the
local lakes on the California coast; nor at the sea shore. This might
be a phenomenon related to the topology and wind patterns of the
Pacific coast, and perhaps other people living in different areas
could give their experiences pro or con.
