I have been to most of the well known kitespots from Cabarete, Brazil, Tarifa, Jamaica, Barbados, Hatteras, Egypt, France, Dakhla, canaries...etc... For me then stand out spot is Cape Town. You first rock up in Cape Town and think "jezus its crowded on the water and just strong megalooping weather" but there is so much more to it when you go exploring. If your temped go this year as the "Rand" is really low, you can eat out in the evening for £5 and get a beach side room for around 15 euro/night.
The real reason it stands out is there is so much more to do when the wind doesn't blow, you have a huge array of other sports, travelling, great food etc... Great weather.
