As Aerbabe says it depends on what you want out of flying. Once you have figured out what you want to do, the next stop is PPRuNe to ask whether it is possible to what you want to do with either PPL. The people on this forum will give you a good idea of which PPL will get you closest you your goal, but we need to know what that goal is first.
Other factors:
Cost - you can do a lot more fixed wing flying than rotary wing due to the difference in operating costs of the two classes.
Kudos - arriving by Helicopter is better than arriving by aeroplane as most people know that it is more expensive! But beware, Kudos closely linked to Ego!
Safety - Helicopters tend to have different kinds of accidents to fixed wing aircraft, you will find many opinions and maybe even some statistics on which is the safer mode of transport.
