We consider a comprehensive set of observables and estimate the associated theoretical uncertainties by studying the dependence on the perturbative QCD scales (renormalisation, factorisation and shower) and by comparing different parton-shower models (${\tt Pythia8}$ and ${\tt Herwig++}$) and matching schemes (${\tt MC@NLO}$ and ${\tt POWHEG}$).
