Hi and welcome!
I have the original Silhouette because I wanted to be able to create my own shapes rather than being limited to cartridges. But I've seen the Cricut and how easy it seems by comparison. I think a lot depends on how computer-savvy you are. They both cut pretty much as well as each other.
Not many people will have both, so you'll probably get answers saying "I love my Cricut/Silhouette because..."!
If you read down this page and the next, there are actually several threads discussing this very thing.
