I liked my 2000 5.4 when I had it.
It did everything I needed it to.
My 2015 6.2 though....no comparison. Pulls much harder for the same or less fuel.
I wouldn't sell a perfectly good running 5.4 just to get a 6.2, but if the 5.4 is tired, I wouldn't buy another one as long as I could afford a newer 6.2 truck.

At no point do they cross.
The VCT is different. The modular engines use a dual equal oil pressure actuated VCT mechanism, while the new 6.2L uses a dual equal cam torque actuated VCT mechanism.
