I'm not a professional, so this is just a personal opinion. I am learing of laminate in a kitchen just because of the water issue and the fact I have children, not sure if this is your situation also. Between the 2 you are considering I would suggest vinyl since it stands up to more, especially water!!
We are putting in tile but our flooring store did show us vinyl that looks VERY much like tile, so you have that option too.

We installed a wood-grain laminate years ago and it has held up very well to moisture and has fared better than any vinyl flooring we ever had to the fine, silty sand that gets tracked inside (despite door mats) by four kids, dog, gardener (me) and husband.

I'll confess, however, that the acoustic properties make for a less mellow sound than either hardwood or vinyl.

A 'quality' sheet vinyl by one of the major manufacturers is something to consider. Most are very resistant to damage and staining and the patterns and colorways are precise and realistic. If you want a good-looking, easy to clean and comfortable floor, sheet vinyl may be what you may want to consider.
