To be as cordial as possible as this is a forum for discussion, I will give Mr Bastid his due. He is talking about engines only, not assembled packages that have been tested . He is correct that Gen 3 hemi blocks and cylinder heads alone using mechanical based carburation systems and none of the engine management electronics won't outperform the wedge motors especially using the W-series heads. Also, the older Gen 2 Hemi's were troublesome, needing plenty of tuning to stay running properly.
But, as the rest of us commented here, when you put together a "package' using the G-3 engine , associated fuel management and ignition systems that are computer controlled, and put it in a plug and play package its unbeatable. No La, BB or Rb engine in its "as produced' format will come close to a Gen 3 for driveability , fuel economy and, in the case of the HellCrate, raw power.
