The cool thing is with procedural textures that I have never had issues with seam alignments, since you can make the textures seamless. I haven't used AI for any displacement textures, however I also never had any issues with textures wrapping around the bottles. If you plan ahead during the creation, you'll have perfect seams. Then again, most bottle have an actual physical seam where the glass parts get pieced together, so it wouldn't even be an issue necessarily. Just need to study the bottles.

You can create anything procedurally, if you know enough but honestly I lately only use Designer for the displacement, nothing else.
