International setup for Markets - What do I choose

[PaMaKa]

We have a domain in 3 Versions:

.com

.nl

.se

I am trying to follow the subfolders method because it was written to be the easiest way to set it up.
What I want though is to give my dutch customers a mydomain.nl and my swedish customers a mydomain.se

to navigate to (and to be able to communicate these url's)

Also I want my swedish customers to see a different logo when visiting our pages.

How do I do this ?
