By their nature, a single LED tends to be quite directional and a point source of light, i.e., it doens't spread out a lot. It can if the lense design is good or they use lots of them. The important specification to look at is the color tempurature...incandescents tend to have more red in them, and are termed 'warm' while some LEDs can be quite bluish, and can make things like food, people look sickly. LEDs tend to be single color and may provide an unnatural lighting effect, although can be quite efficient while doing it. Since different people perceive colors in different ways, sometimes the only way to tell if it's a good match for you, your cabinets, counter, etc., is to try one. Also, if they try to push lots of current through the things, the design of the heat sink is important - keep the heat managed and they can last 10's of thousands of hours, but overheat them with an inadequate heatsink, and they could expire rapidly. Sorry, I can't be more specific...I've not looked into these much. When I did my remodeling, I chose a mini track with low-voltage bulbs. I did put them on a dimmer (and I recommend you look at lights that CAN be dimmed as it can really set up the mood) that works well. Mine are low enough profile that you only see them if you are sitting down and can look up at the underside of the cabinet, and then not by much since they are near the front edge of the upper cabinets (to get them centered on the counter and help provide more even lighting) since the track and the fixture are quite shallow.
