which Online payment gateway to pick up?

Hi guys,
I want to open an online shop and I want to know which payment gateway I can implement on the website best. I've searched on Google but there are many payment gateways. I want to hear your experience. Beside PayPal, which Online payment gateway do you think it's great?
The payment method should accept major credit cards, bank wire transfer (optional), affordable transfer fee.
Thank you.
