Lever buckles are faster to lock and unlock at the same tightness every rep, which specialist powerlifting communities cite as ideal for max-effort singles. Prong buckles (single or double) are more flexible day-to-day because you can adjust the tightness across sets without unscrewing the lever. Lever screws can also loosen over time — multiple reviewers we read recommend applying Loctite.
