Help me choose my new Sub Ohm Tank.

Hi there (:

So I’m going to purchase a new mod and tank very soon. I do vape 0 nicotine e liquids, so I do mainly care about flavour reproduction and intensity.

What tank and coils would give me better flavour between the Geekvape Aegis Legend 5/Z Sub OGM tanks with z xm coils and the Voopoo Drag 5/UForce-X with PnP X coils?

Thanks in advance!
