I have the Kumho Ecsta 4X and love it. Ride quality is soft (I am dropped on Buddy Club n+). No real road noise, and the car feels more planted on hard turns. (I have an alignment to oem spec in the rear, -2 deg camber in the front with toe at 0.00 all around. Tire pressure is at 32 psi cold in the front, 29 rear)
For me, it came down to the Continental DWS versus the Ecsta. I liked the treadwear rating on the DWS at 540 (versus 420), but couldn't justify the higher price ($142 versus $116 (-$50 rebate at the time).
The Kumho's got better ratings for road noise, which is a plus point for me. In the end, factoring in that the 'Snow' tread depth wears out quickly on the Continentals (which could mean that its ability for traction in light snow could wear out even prior to the tires seeing its first snowfall), and the fact that the sidewalls are soft, led me to go with the Kumho. NYC is pothole haven.
This is just my review. I've driven on them for about 4,000 miles.
Obviously if your budget allows, you can probably get better tires. I previously had Goodyear Eagle F1, which cost more, yet I hated. Too soft of a sidewall yet a very firm ride. Noisy too! If money wasn't a factor for me I would probably have Pirelli P-Zero Nero's, or Bridgestone Potenza Pole Position, lol.
EDIT: I also believe that the Continentals were the lightest weighing tires in my comparisons.
