Everyone posting about how Lammys are "faster" seems to be forgetting something. Your delay doesn't go below 10, or one second, no matter how many haste items/buffs/percentage of haste you have. Since a lam is so low anyway, you can only reduce it's rate about 50% before hitting the min delay cap. Your weapon becomes 9/10.
The Centi and other high-damage but "slower" weapons can take greater hastes (which at 50+ you're going to get with any group that has a chanter in it, esp. if you've got a haste item.) At the same 50% delay reduction the centi becomes 15/13 at 70% it becomes 15/10 (technically .8 but the min delay cap again.)
So yes, this is superior weapon when there's haste involved.
