I have always been a believer in Ethernet as opposed to USB for networking. I have a cable modem that has both Ethernet and USB so I decided to test it for anyone who's interested.
The first three results are from USB. (Hey, I coud not believe it worked in the first place so I figured I better test it before it breaks.)

The next set of tests are Ethernet, I had the computer connected through my router for this one.

Now I decided to go straight to the Cable Modem Ethernet Port for these next tests just to see if it makes any difference.

For this last set of tests I wanted to see what my wireless adapter would do going through my router.

The conclusion...
It appears that there is no noticable difference in the speed. I prefer the Wireless adapter due to the mobility, which in my case also uses ethernet to connect. So I guess I'll stick with ethernet for now.
Someone with a fatter pipe my be able to find the speed barrier. I don't think I have reached the speed that's required to max out the modem as it has a 100 Mbps Ethernet port and is capable of 42 Mbps download.
For greater reliability I would still go with ethernet.
One thing I can say is if your still using the old clunker that came with your service contract a few years back you should upgrade to a newer one.
