I use the oscillating hoe, a copper one from PKS, called the hydra. It slices through weeds like butter and will easily drift down an inch or so if required. The benefit of both pushing and pulling the hoe is twice the area covered for the effort. I use a dutch hoe when I want to be dipping around a bit slower, or into heavier ground. However since most of the beds are relatively young and soft due to being compounded by myself the copper oscillating hoe is the go to tool.
