Oppo Help *updated*

Getting my flights for the Eagle Rally 2019

On my flight over (nonstop) I will be aboard a 787 Woo Hoo!

The flight back though I have two choices

1. Heathrow to Amsterdam(737) then to LAX (747)

2. Heathrow to Charles De Gaulle (A321) the to LAX (A380)

Neither of which I have been on before and I can’t decide which to choose.

I am leaning 747, but I want Oppo’s opinion

UPDATE:

Flight home is via CDG and Airbus
