It's all good "wind sports". Many season now kiting it's much easier, not as wind hungry as windsurfer and less kit. 12m kite and surfboard gets me out in 14knts. 8m kite over 19knts. Travel with family, limited car luggage space kite is great. Boosting with a kite

. Much easier through shore break.
But I'm still a windsurfer through wooden booms, "new toys" "wind action" and now starboard.
nothing beats wave riding with a sail. float and ride windsurf kit has competent sailors out in 12knts and surfing way before kites can launch.
Modern sails are so hi tech in fabric and cut, the wind range is wide my 5.3m / 4.7m / 92ltr board almost covers conditions.
foils are next level can't comment my learning is still infant.
setup kites need space. Lines out, launch / land. Can be on the water quicker than sail if I have a clear area.
witnessed some scary kite launches in crowded areas. Sails no problems in tight spaces.
I wash kite lines, kite bar and rinse safety, not kite. Windsurfing don't wash sail but boom, universal, extension I wash in fresh water. Set out and pack up, windsurf longer.
cost and equipment failure.
sails bit cheaper than kites (2nd hand or run out, usually my buys) I'm not tough on gear, probs boring on pushing new tricks.
kite bar and lines also bit cheaper than universal, extension, mast and boom. Kite boards also cheaper.
Universal joint (tendon) I replace each year. Kite safety line I replace every 2 years.
