My PS3 with HDMI to DVI looks crystal clear on my monitor, but my 360 (VGA) is noticeably less sharp. If you can go the HDMI/DVI route, do so (you may even be able to do 1080p and scale down, which should look better than 720p).
It can also have a lot to do with the way a monitor handles the signal. In a perfect world, VGA is very good. However, some monitors don't do a great job with it. It also is going to have a lot to do with what resolution your monitor is, what resolution you are sending it (remember the xbox VGA is very limited as to what resolutions it can output... there is nothing between 1360x768 and 1920x1080), and how good your monitor is at scaling the image. I can tell you right now that there is no noticeable difference on my TV when I connect my Xbox via VGA or my roommates xbox (elite) via HDMI. However, I have seen certain monitors/TVs where a certain input was poorly designed (IE: stuff looked great on HDMI but bad on component, and good on VGA, or bad on HDMI, but great on component, etc...). As HDMI is pretty much the current standard, it's often best to use that if you have it available. However, many sets still offer very good support via component along with VGA and these analogue signals may look quite amazing.
Of course, if your monitor doesn't have 1:1 pixel mapping, and is at a resolution between those offered by the 360 (quite likely unless it's a true 1080p set), you are also limited by the monitor's ability to scale the image. Some monitors are great at this, and there are a few that blow goats. Furthermore, on a 16:10 computer widescreen (as opposed to 16:9 HDTV), you will have some stretching if your monitor doesn't support 1:1 mapping.
