Be careful of the type of taxi you end up in. We landed after midnight and there was a 50% surcharge (midnight to 6 am), and I ended up in a Mercedes (after lining up at the regular taxi line) which was another premium rate. I paid over $50 sgd for my ride! I had actually initially tried to get grab but no one would pick up my request. Went into the long taxi line after waiting for 30 mins for a grab. BTW, the changi shuttle is now operating during peak business hours now for only $10 sgd per person, but very limited hours: https://www.changiairport.com/en/air...e-airport.html
