The only correct answer here is Alderaan. And not because of the story or the scenery or any other such nonsense. Because there aren't hardly any frickin' speeder points on the entire planet. You have a bunch right near the starting area and then it's a day's ride on your slow ass speeder to get all the way across the map. Only to find out there still aren't any taxi points.
I did my class quest stuff there and then GTFO.
