Currently using only Citi Premiermiles,not sure which cc next to go for (missing out all the 4mpd goodness), what would your next cc recommendation be? uob ppv? concerns re expiring miles?

I just signed up for Citi Rewards Visa - Great 4mpd for up to 1k spend per month, and long expiry dates.

I would take the citi rewards visa as the rolling 5 year expiry will be useful to accumulate a critical mass of miles, but you must keep track of the expiry date and redeem them before they expire!

It's also within the Citibank ecosystem, so you don't affect your new to bank status for other cards if there should be a fantastic sign up offer on another card down the road.

Many cards offering 4mpd for spending in selected categories as others have pointed out.

For generic spending, you may want to look at uob prvi visa or master for the higher mileage (1.4mpd), especially if each spend is typically above $30

You can try citi rewards visa or uob preferred platinum. Especially with grabpay becoming a super app, the ability to hack miles at 4mpd via the 2 mentioned cards is now open to a lot of possibilities
