Seriously though...
How many of us actually practice shooting and cycling the bolt from the shoulder for the next round? I admit that I haven't!
My own experience, however, is that my Marlin lever seems to be easier and faster than any bolt action I've tried. Some bolt actions take considerable more effort than others to cycle, too, which I often read is one of the drawbacks of a three lug bolt...sometimes a bit harder to cam the bolt open on a spent round than most two lug bolts.
Of course, the biggest screw up that happens with either, usually when confronted by a potentially dangerous situation and the adrenaline is pumping like hell, is short stroking the action, not picking up the next round, or God forbid jamming up the works...and I'm inclined to think that this happens easier and/or more often with bolt actions than lever guns.
