I have used European hinges on several sets of frame-less kitchen and utility cabinets. I like the flexibility of adjustment they provide. One drawback is the cabinet side of the hinge is only supported by the screws. I have had screws loosen and the doors sag. Over the course of time and after a few tightenings, the holes wear out and need a little more attention to fix. This has happened on cabinets made with MDO and plywood. It might not be a problem with hardwoods. When I use them now, I add a little epoxy to the screw hole to keep them tight.
