Helicopters are more often than not more experience to rent than aeroplanes. I dont know why that is, but it seems to be the case most of the time.
I fly aeroplanes, and as you’re just wanting to fly for leisure i’d suggest saving your money and going for the PPL/A or even the NPPL (This is normally cheaper than the PPL) However, the factor of expenses purely comes down to your situation, if you have loads of money to burn and prefer choppers, go for them.
Go and talk to a few flying schools over at Stapleford and also North Weald. See if they have anything taylored to your needs, or even supply you with the relevant information to help you make your decision.
