I have had my Linksys for about 8 months now, serve 4 systems at home: 2 windows and two Macintosh. Never had a problem!! the Linksys has a very manageable interface. I can only image that the Netgear would be an equal product.
At my work I have Asante and Linksys, both play together very well.
The plastic of the Linksys has never bothered me. My router at home, as well as the switch at work are in closets, or hidden. The look of te unit is not as important as the reputation of the manufacture, the type of warranty, and the type of tech support that you are going to get from the manufacture.
Linksys has been great for me and I would put it at a client site!!!
