Depends on what you do with the image.

If it is for display on the web: subject, composition, then practical considerations that affect the appearance of the image (focus, exposure, colour, resolution, etc.).

If it is for display in a small print: much the same, with maybe a slight increase in the relative importance of the technical issues.

If it is for display by digital projection: same as for the small print.

If it is for display as an optically projected transparency then the technical requirements are integral to the result, as that mode of display emphasizes faults - it may be that bad technique is enough to outweigh good subjects and composition.

If it is for display as a larger print then the technical requirements are integral to the photographic artifact, so the answer will depend entirely on the intention of the photographer - some will want a print that is like a transparent window to the scene, while others will want something where the qualities of the medium are most important, and themselves a source of beauty and wonder.
