Benro QR plate
I'd just get the RRS plate for the cameras involved. RRS points out that they recommend only a limited selection of sources for use with their lever assembly. Unlike the screw type assemblies, the lever release has more limited range of adjustment. That $40 or so saved up front won't look so good if you have an equipment crash.
