  We compare different jet-clustering algorithms in establishing fully hadronic
final states stemming from the chain decay of a heavy Higgs state into a pair
of the 125 GeV Higgs boson that decays into bottom-antibottom quark pairs. Such
4$b$ events typically give rise to boosted topologies, wherein
bottom-antibottom quark pairs emerging from each 125 GeV Higgs boson tend to
merge into a single, fat $b$-jet. Assuming Large Hadron Collider (LHC)
settings, we illustrate how both the efficiency of selecting the multi-jet
final state and the ability to reconstruct from it the masses of all Higgs
bosons depend on the choice of jet-clustering algorithm and its parameter
settings. We indicate the optimal choice of clustering method for the purpose
of establishing such a ubiquitous Beyond the SM (BSM) signal, illustrated via a
Type-II 2-Higgs Doublet Model (2HDM).
