The RRS foot, for better balance on a gimbal while retaining handle function. I eliminated the Wimberley replacement foot as it can't be used as a handle. I'd never heard of 4th Gen Design, but looking them up, I learned that's the maker of the Mongoose side gimbal, of which I've certainly heard. Although the pic is tiny, it looks much like the Wimberley 'foot' - too flat to be used as a handle. I believe that is a consequence of the Mongoose and Wimberley side gimbal designs. RRS doesn't have that issue, since their side mount gimbal (which I have) can be adjusted horizontally to center the lens, as opposed to the one-piece design of the others.
I'm not sure what Canon was thinking with the tripod collar on the 600 II, and the 500 II seems even worse. Basically, the Canon foot is too far forward. It's fine with just the body, but when you put a 1-series or gripped body with a 2x TC, the center of mass is right under or very slightly behind the mounting screws on the tripod collar. The problem is the Canon foot sweeps forward, and a Wimberley P-50 doesn't sit back far enough. The Kirk foot is designed just like the Canon foot, with the forward sweep. The RRS foot can be used as a handle, and actually extends slightly behind the mounting screws on the collar. With the 2xIII and 1D X, the back edge of the foot is flush with the back of the 80mm RRS clamp on the gimbal at the balance point. So, with the Kirk foot or a Wimberley P-50 plate on the Canon foot, the back edge of the foot/plate would be inside the clamp - probably still plenty stable, but I'd prefer to use the full extent of the clamping surface. Alternatively, with it flush the intrinsic tension/resistance of the head would probably compensate for it being slightly off-balance - but I'd prefer it to be properly balanced.
Probably more detail than you wanted... ;)

Spotted Munia (Lonchura punctulata) by alabang, on Flickr
The Scaly-breasted Munia or Spotted Munia (Lonchura punctulata), known in the pet trade as Nutmeg Mannikin or Spice Finch, is a sparrow-sized estrildid finch native to tropical Asia. A species of the genus Lonchura, it was formally described and named by Carl Linnaeus in 1758. Its name is based on the distinct scale-like feather markings on the breast and belly. The adult is brown above and has a dark conical bill. The species has 11 subspecies across their range and differ slightly in size and colour.
This Munia eats mainly on grass seeds apart from berries and small insects. They forage in flocks and communicate with soft calls and whistles. The species is highly social and may sometimes roost with other species of munias. This species is found in tropical plains and grasslands. Breeding pairs construct dome-shaped nests using grass or bamboo leaves.
The species is endemic to Asia and occurs from India and Sri Lanka east to Indonesia and the Philippines. It has been introduced into many other parts of the world and feral populations have established in Puerto Rico and Hispaniola as well as parts of Australia and the United States of America. The bird is listed as of Least Concern by the International Union for Conservation of Nature (IUCN).

Little Egret (Egretta garzetta) by alabang, on Flickr
The Little Egret is more delicate-looking than any other heron-like bird which occurs in Britain. It is much smaller than a Grey Heron, with snowy white plumage, a long pointed black bill and black legs with strikingly yellow feet.
Habitat
Feeds by the edges of lakes, reservoirs, rivers, brackish lagoons and saltpans. Breeds in waterside trees and bushes.
Behaviour
The plumes which are present in spring serve to emphasise the threat and appeasement gestures given at the nest.
Migration
Most of the European population migrates west and south, mostly to north Africa but also, to an increasing degree, to the european side of the Mediterranean and the Atlantic coasts. After fledging, juveniles disperse almost randomly from July to September. This movement is presumably governed by prevailing feeding conditions.
