Albania/ which place to stay longer?

Hey guys, I’m travelling to Albania in a month. I’m planning on staying in Berat, Vlorë and then Himarë. Vlore is just a stop off for a night.

I was wondering, is it better to do 3 nights in Berat, and 2 nights in Himarë. Or the other way round?

I am only there for a week, so any help would be appreciated.
