I was in a similar situation back in 2Q 2019 - JS vs PE. Shared my views earlier in this thread too. Concerns pointed out here are mostly valid. Though perhaps i think the 'weekend gatherings' mentioned is worst @ PL, not so much @ Eunos.
Love JS for its massive facilities and near Thomson. I think traffic is bad for both locations - esp during peak hours. But chosen PE ultimately due to it's lower pricing and higher chances of appreciation. Bought for own stay, but easier to sell/rent in case we have a plan B since it's nearer to MRT (East/West line) and in between CBD, PLQ and Changi business parks.
And someone mentioned, I do prefer central/east than central/north.
Happy with my decision so far since PE has much better take-up rate and prices have been increasing (1-2%) already. Maybe with the JS discount there is more value now, can go do more studies. I am thankful that I did not buy JS then, imagine knowing your project has a discounted price after you bought. I reached out to QingJian to enquire back then, they say they will not drop price as they are liable to buyers.... well.....
