There is probably not a huge difference. Personally, I have always used Linksys and have never had a problem at all. One time I had an issue that I caused and I called their customer support and they could not have been more helpful. Linksys also makes nice range extenders if you need to push the signal further in your house. I had to do this to get to all of the upstairs areas. They are very easy to set up. Since I know Linksys, I would reco them, but Cisco may be just fine also.
In addition, I know a lot of other people using Linksys and they are all pleased as well.
