Of course there wont be (m)any hitting the "New" choice, as they are not present on this forum.
And there are MANY new wingfoilers, who havent done any other wind board watersports.
Which is the most fun kite or wingfoil - makes no sense for me to judge, it is ALL fun, and feel good both/all of them, but hugely different in many ways, ALSO the good feel
There are some differences for me, here the positives of both as they are for me:
Wingfoil is more physical, for your arms and upper body, a plus, and still not so much that you get tired fast.
Wingfoil is better and safer in shitty wind say a bit offshore (or a lot).
Wingfoil is far better in some spots like harbours or similar, where you dont have access or room to launch a kite, or where too risky because of masts.
Wingfoil is, for most, learning something fun and new, always good.
Wingfoil is not as risky if the wind suddenly goes nuclear, or you make a mistake.
Wingfoil can give you a very free powerless great feel when surfing a wave.
Kitefoil only takes up a fraction of the space in your car, lighter and smaller, if walking to a spot, as no pump needed.
Kitefoil is way faster and easier to rig and get out fast, beats wingfoil by miles, also a tad faster setting down and packing.
Kitefoil is easier and faster to get out through the whitewater in waves, and if needed you can start faster between two waves.
Kitefoil is a lot more agile and low drag and you can turn tight and lively on waves.
Kitefoil let you pack your kite dry, as opposed to wing which is wet when you pack, and if you use several wing sizes, they all end up wet in the car.
Kitefoil can ride foiling in a lot bigger windrange downwards - you can still start if the wind drops, unlike on a wingfoil where there is an absolute individual lower limit, where you are parked for good if no gust.
