As I understand straight is the strongest, but if there is no movement in the joints the U-joint caps, trunions, and needle bearings will have all the wear and tear in the same spot causing flat wear spots. Once wear has occures, it will be noticed when the driveline is removed there will be a noticable catch or hesitation when rotating the joints and caps by hand. Easy to move and smooth with no rattle or shifting is the desired feel. Just the drag of the grease.
