Advantages of Cashier over simple Stripe SDK?

We are building 2.0 version of our website in Laravel and I cant help but notice Cashier. Our current website is built using Wordpress and a messy plugin using the Stripe php wrapper very heavily. I already have most of the billing functionality coded up in the Wordpress plugin including a reliance on subscription schedules in a few places which I'm seeing is not yet supported in Cashier. However I need to do some refactoring of the code and clean a lot of things up while moving it from a Wordpress plugin into Laravel. I'm trying to decide if I should use Cashier or not and would love to hear what people have found the advantages and disadvantages of using it over just the php wrapper that Stripe provides.
