Ossus the most, simply because it looked pretty and I don't think it was shown to have dangerous flora or fauna.
Tython the least, because travelling around the Deep Core would terrify me, and I wouldn't want to spend all of my life on one planet with limited visitors.
This is so easy. Do you know what porgs are? Yeah, why is this even a debate. I have the lego porg companion in Skywalker saga and a huge pop bobble head one on my desk. I also have my season 2 Omega fig petting little ones. WHY IS THIS EVEN A QUESTION THE ANSWER IS PORG. (And don't say anything about eating them or I will find you.)
