Ceramic tile over old vinyl
Just something to think about since you'll be adding some thickness to your floor. Any trim or moldings will need to be mounted higher, and if you have any doors or pantries that open into the space, they may need to be trimmed as well. If you have an air duct that exits from under a cabinet, it may no longer fit.
Ideally in our kitchen, I'd take out the floor and put in ceramic, extending it into the dining area (which is now covered with off-white carpeting...NOT smart for a dining area with younger kids!). And I'd also think about doing the ceramic tiles with the grout lines on the diagonal. Granted, a lot more work, but it would be unique!

Plus, as someone else pointed out, you loose room space by not removing the old flooring.
