Do you crab or forward slip in X wind landings

Side slip is the easiest and most powerful form of crosswind correction.
Simply use the rudder to keep the nose of the glider parallel to runway
center line and lower the upwind wing enough to counter the wind. To much
bank and you drift upwind of centerline. Side slip can be maintained all
the way to the end of the roll out just by keeping the upwind wing low.
If
the cross wind is to strong for this method you shouldn't be flying or
you
should select a different runway.
Crab Requires a transition to a side slip just above the ground and
almost
guarantees a side loaded landing either from kicking to late or to soon
and
not getting into the side slip quick enough.
Forward slips are not really for crosswind correction they are more for
glide path control.
I wonder about the different methods that are taught - in Europe the
only acceptable method is crab, aligning with rhe runway heading
during the flare, and immediately touching down. Priority is to keep
the wings level all the time to reduce the chances of a ground loop in
case of an outlanding.
Is it grass strips vs. paved runways which we don't have in Europe?
Just a question (since I fly a glider where side slip would always
drag the wingtip on the ground before the main wheel touch down):
How do you cope with one wingtip lower than the other in case of an
outlanding on a field with higher crops? To me the side slip method is
a recipe for disaster in this case...
Do you teach both methods?

I think it depends on what you are flying and the surface you are landing
on
The modern ships like Ventus 3 and arcus seem to have high wing tips as did
the early American stuff so slip makes sense
The kestrel,nimbus generation ships had low tip clearance and a crab was
the
only way.
I was once told the are only 2 types of Kestrel owners ,those who have
ground looped and those who are going to
Nice soft grass is much more forgiving of a little sideways slide than high
friction paving
