Suggestion: read the specs of all the power supplies you are considering, make sure you know the capabilities and limitations of each. Then compare that with your requirements - what pedals you're using or intend to use in the near future with said power supply and whether each power supply can cope with it; whether you intend to use the power supply to power everything or are you content to plug in an extra wall wart; where are you placing and mounting the power supply (eg the PP2+ is a great pairing with Pedaltrain boards because of the design of the boards) etc.
Finally, factor in price. Is the price difference a huge deal? Which is more important to you, getting the functionality that suits your needs, or being thrifty and conserving every dollar? Is the S$150-200 difference going to be a dealbreaker for you? If so, can you take holding out on a new purchase in order to save up for what you require and how long will it take and what do you have to do in order to earn the necessary?
Then consider all the above and finally make your decision.
It's kinda simple when you think about it systematically.
