Shadow is the new one for EU

https://eu.finalfantasyxiv.com/lodestone/worldstatus/

Worlds are no longer defined as new there. It’s not a matter of date of creation of the worlds but of population.

Materia would be the best choice if you have friends on the EU worlds as they could take advantage of cross region travel to play with you on Materia.

Or just chose the one with the best ping. Someone who creates a character on Dynamis can also DC travel to Materia when they want.
