Laravel Omnipay/Payum Detailed Tutorial

Has anyone here have Laravel Omnipay/Payum tutorial in detail with the case of supporting Payment with PayPal, Stripe and other Payment Services?

I've searched it, but only found Laravel with PayPal only (Omnipay), and the tutorial also not so in depth

I don't know how to use Omnipay/Payum with Payment Services such as PayPal/Stripe or any other

And if you ever used Omnipay and Payum, which one that you prefer ?

Thank You
