First choice: Michelin PS4, absolute best for now!
2nd: Continental CSC5, the best before PS4 came along.
3rd: The new Goodyear F1 Asymmetric 3, maybe slightly less performance than the above but still way much better than your Assurance and probably the quietest high performance tire now. Beware that the price is still around rm600 for that size coz still made in Germany!

Other notable choice:
Yokohama Advan Fleva, should be way much cheaper than the 3 above but should still give higher performance than your tire now.
