Depends on how much rudder authority they have at their disposal whether or not they even have the option to slip it straight in.
The landing gear is built to take a bit of side load like that, and aircraft with low-hanging engines don’t have the slip option anyway. Most every “radical crosswind landing” video I’ve watched features commercial aircraft crabbing them in.
I was taught to crab it down to the runway, then kick it out, flare, land. I was shown the slip method, but to me it was more difficult.

Always had my gut up on those...seeing the runway at a 45Degree angle is interesting...
Same here.
