I have to smile. The cost of either of these starter kits is small potatoes when you are considering taking up flying as a hobby or career. Buying stuff on Ebay is fine if you don't mind other peoples' dog eared stuff, which may have been goodness knows where!
The bulk of the costs of both kits is in the books. Which of those two series is chosen is down to personal preference. They both say the same thing in slightly different style. Occasionally, you will find a small point which may be out of date. Your instructor will almost certainly put you right, and there is the internet, etc. You will buy other books - definitely!
Hardly anything in those kits will not be used in your training. You need the map. You need the logbook. Yes, the knee-board may be sub optimal, but it will do as a starter. Your needs will change as you progress in the hobby or career, and so you will replace it. You will love a new and better flight bag, so you'll eventually choose and get one, and then another one.... You'll rarely use your square protractor (a plotter is better!), the flight computer, and some other items later, because you already own a far more expensive iPad, a computer and so on - on which you'll have perfect wind corrected flight plans with the lines on the map that you will plan. Your flight log will be printed by you - but not yet! You do the PPL the traditional way... Some of it may seem (and is) somewhat anachronistic, but the principles learned will serve you well.
You will need most of the items in either of those kits - these have been standardised for years, and are similar in the USA. Both Pooleys and AFE have been in the business long enough to know what the basic requirements are. As I've already said, you will buy other bits when you see that you need or prefer them.
Get the best headset (ANR is really recommended!) that you can afford. A good one will last you for years. Do try and visit a pilot shop to try these out. One size does not fit all
