It is not a surprise, really. Text properties are much faster than
overlays, and very close to them features-wise. They are a bit more
complex to handle, however.

You cannot. You may however mimic it with `cursor-sensor-functions' text
property. These assume Cursor Sensor minor mode is active, tho.
I haven't tested it, but I assume it would slow down text properties
a bit, too, but hopefully not as much as overlays.
Note there are clear advantages using text properties. For example, when
you move contents around, text properties are preserved. So there's no
more need for the `org-cycle-hide-drawer' dance, i.e., it is not
necessary anymore to re-hide drawers.

Missing `isearch-open-invisible' is a deal breaker, IMO. It may be worth
experimenting with `cursor-sensor-functions'.
We could also use text properties for property drawers, and overlays for
regular ones. This might give us a reasonable speed-up with an
acceptable feature trade-off.
Anyway, the real fix should come from Emacs itself. There are ways to
make overlays faster. These ways have already been discussed on the
Emacs devel mailing list, but no one implemented them. It is a bit sad
that we have to find workarounds for that.
