Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?

Actually, '09 was the start of the newer "Eagle" 5.7 and it's more the Eagle 5.7 that is destroying cam/lifters. At the PD I retired from, I last bought new Chargers in '18 and the new guy has bought some '19s and '20s on order. I keep in touch and will be finding out what the newer cars are experiencing. I think it was through at least '14 year models that they were giving me fits, because they had enough mileage on them for the problem to occur.
You are more of an expert than I that's for sure.

I do know that the new design from Johnson oils the roller bearings better than the OE design and they claim tighter manufacturing tolerances take the tick outta the valvetrain.

I have 5 Gen3 Hemis in stock right now. 4 are early motors. The PO's of two non mds engines proudly stated they used 15w40 oils to avoid lifter issues. Both had cams destroyed...
