Define what is attractive to you. Both have very different career routes.

DXO EA can rise through ranks and files to assume bigger appointments. While in the past, it was uncommon for DXEAs to rise to DX9 & above, it is getting more commonplace now. I have a colleague who was a DXEA and is now on a DX9-11 job band. Which means, she through her merits, can rise to DX11 in this appointment.

Also, DXO scheme does not differentiate between DXO (Officers) and DXEA (Non-officer) now. Everyone is on the same scheme, to accentuate the above point where deserving individuals, no matter where their entry point (diploma, A-levels, bachelor's degree) is can be rewarded by taking on bigger appointments.
