I have not handled the Doomsday handle, but I do have the NDZ and Tacticool22 handles, and they are both quality pieces.

The only thing I would take into consideration, is that the Tacticool22 does not come with a new latch and is made to accept the factory one. NDZ does offer a handle/latch combo or you can purchase the handle by itself and use the factory latch.

As others have mentioned in this thread I do offer a few different drop in latches that will work with the NDZ, Tacticool22, Plinker Tactical, and the original factory handles.
