Which should you choose?

We will not advise between these two machines, because their power is identical, with the same weight or the same engine, which usually means one machine sold under two names; any difference below comes from how each source describes it. The figures below are side by side so you can judge them yourself; each says whether it was measured, claimed or declared by its source.
