Best Shopping Cart, reviews & suggestions please?!

[Moh1]

Now while I soon will open my electronic shop I would need to know which shopping cart is the best, easy to use and most reliable and secure one?

It should be flexible not to complicated to setup and need to have no restrictions on the number of items, sub categories etc.

So far I have been looking at OSCommerce, ZenCart and Virtuemart all 3 of them are really great but don't know if there is anything better or if the mentioned carts may have security problems..

Also when you post let me know what options for credit card processing it has, thank you.

OSCommerce next to Zen-cart has the most supported payment gateways what so ever, don't fall for the noname ones, they are simply not worth it.
