Back in the 90s when I did my glider pilot licence it allowed me to reduce the hours of the PPL course almost to a point where I had two licenses for the price of one...
The advantages of getting the early knowledge of flying in a glider is a great base that will stick forever with you.
I am not aware of the regulations now, if you still get a reduction in the PPL hours by being a Glider pilot, go for it.
