Hi Raphael,
>Is there a page that describes the differences between the 2?
Your best bet will likely be to go to the respective Features pages and compare... Or better yet try them out.
Whatever you read is usually not enough to make a decision anyway, so trying the products is probably the best way to get a feel of how things work.
The problem is that any sort of comparison usually is biased one way or another depending on who's doing the comparison <g>...
