I'm not seeing any leaf distortion that you referenced. In any case, rotating a plant does not mean that it gets any less light, particularly if the plant is rotated a quarter turn each time you water. Leaf formation is largely determined by the light that a leaf receives when it is first emerging. Rotating a plant is the best well to keep growth even and preventing lopsidedness.
Once a plant starts to become lopsided or very tall and in need of support, it should be pruned. Pruning does not in any way affect the health of a plant, but it does help it look better and keep it from becoming overgrown and top heavy. The stems of both your plants can be cut back at any place on the stems. New growth will slowly emerge on the cut stems just below the pruning cuts. Pruning keeps a plant fuller and more compact.
PInching is an alternative to pruning if it is done before the stems become too long or unwieldy. Once a stem is at the length that you prefer, simply pinch out new leaves as they start to emerge. You will have to do this regularly to maintain it at that size. Like pruning, pinching does no harm to the plant.
