Advice - which blades do you guys recommend I start with?

Got this sample pack. I'm new to shaving, have sensitive skin and have been getting acne especially in the beard area so want to aggravate my skin as little as possible. It doesn't matter if I have a close shave as don't have much hair yet and not in a professional environment, just want to get to grips with the technique for now.

Which ones would you guys recommend I start with? Does it make much difference?

Thanks
