The only real thing the one hand plant reverse or forward high kick has going for it is the element of surprise, mainly due to the fact it isn’t a commonly used technique and so your opponent might not react in the correct manner.

However, that is about all it has going for it. Not only does it completely destroy your center of balance thanks to your leaning over on one hand, it robs you of any defence against a counterattack, as your hands are now completely misplaced and worse still, you have left the back of your stationary leg and buttocks area completely wide open.

In other words, do it fast, land the blow and hope to heaven that your opponent is caught easily by surprise and has mercy on you by not planting his foot squarely in your buttocks!
