QR systems are technically superior: the axle is under compression, not tension and will resist forces better. If it does ever crack, the QR will hold things together better than a bolt.
Actually, with a solid axle, only the parts of the axle between the locknuts and the axle bolts (the width of the dropout on each side) are tensioned.
