For the phase space slicing method we study the effects of improvement terms that remove restrictions on the slicing parameter s_min. For the dipole method our comparison is a first check on some of its counterterms involving massive quarks, derived recently. In our comparison we address issues such as numerical accuracy and efficiency.14 pages, 7 figures, 2 tables, additional references and comments addedHigh Energy Physics - Phenomenologytext
