RJ11 to RJ11 shielded cable better than router supplied?

Been having a look at Belkin High Speed Internet Modem Cable 2.1 meters (Part # CC3011aed07) for connecting the router to phone master socket with filtered face plate. Replacing the thin plastic covered one that came with router.

People that have used a third party cable did you notice any improvement? And what brands have people used?

If you have a particularly "noisy" house then it MAY help, otherwise it's unlikely.

There are a lot of people that swear by them, but it you think that upgrading the last 6ft of a 10,000ft line that could be picking up noise along the way, it probably going to show little / no improvement.
