Given the same magnification a same sized focal length macro should give you roughly the same field of view and working distances. There will be some variance due to where the optical center of the lens is. A macro lens is basically a very flat field lens on a built-in variable length extension tube.

Most dedicated macro lenses rarely give more than more than 1x magnification without a diopter, TC, tubes or a bellows. The most notable exception of this is the Canon MP-E 65mm 1-5x Macro Lens which give up to 5x magnification without tubes, bellows or a diopter.
