We present a comparison of two highly optimized methods for extracting the topological charge density of a lattice based on smoothing away non-topological fluctuations. The methods are Improved Cooling and Hypercubic Smearing. We find that while the two methods differ significantly in their philosophy and formulation, they produce surprisingly similar results after a few sweeps. This supports the notion that, at least after the initial sweeps, the surviving topological information they produce is physical.
