I like LinkSYS. I have one of both "B" and "G".
The range on the "G" is a better and doesn't get degrade in the sun. I noticed that when I was out in the backyard on a sunny day my "B" would sometimes lose it's signal.
Internet speed...no difference. I do notice a difference when I play games on the "B" router, a little higher ping on the "B" wireless when compared to the "G".
