You can see from the comments that it really is a matter of taste. We now have a [Doppelstabmattenzaun] and have ordered the same for the new property (partly with privacy screen where the pool will be). The fence is stable when the children climb on it, low-maintenance, and can be greened.
A hedge is nice, but takes a long time to grow, you have to water it diligently, and it takes up a lot of space. There is already a hedge on 2 of the 3 sides of the property and you easily lose 1 meter.
If you need privacy, you can plant ivy. It grows quickly and becomes completely dense. My neighbors did that and it looks good. Nowadays you can also plant something different or plant other plants in front of the fence to loosen everything up.
