I owned a set of Dive Rite fins and didn't like them as much as my Jets. They were longer (not so good for tight spaces) and didn't seem to have the same thrust as the Jets. If I didn't have a set of jets (say I lost one), I would consider buying a set of the OMS version - they are much lighter/less negative and when I tried a buddy's they seemed to kick pretty similar to my jets.
