Eps is more of a bigger pain, when the motor or torque sensor fails, you need to buy the whole thing again.
The drainage you mention is done in all metro cities and is called road crown. This is why your alignment spec should be followed rather than the dumbass shops trying to defy the factory spec and making the car roll straight on flat road.
I have owned multiple cars and still own cars with hydraulic steering. They are perfect and always have been when I do their required maintenance and keep them in good shape.
Now if I get dumbass to align it or drive with extreme bad camber and then cook the pump and rack, its my own fault, in similar case with eps, i will blow the torque sensor, which again is not cheap.
Why go through a hellish expense on a scrapyard sourced job when you can repair the original fault cheaply
And to top all, eps cars feel like crap, zero road feedback
