Which payment plugin to use?

Hello, I am trying to select the simplest payment plugin to use....

I want to offer a free trial for store owners, then a paid subscription. I also want the plugin to offer a sign-up page that lets me create an easy comparison sign up list without much coding.
Eg like these sign up pages.
Eg https://www.shopify.com/services/signup

Too many choices! Which payment plugin does this?
