I like far left just because it's easier to rest the snowboard while going up (goofy.)
+1, I'm worried about how my ankles and feet feel on the lift than how I'm going to get off... I'm goofy and try to sit on the far left as much as possible. It is marginally easier getting off on the far right.
Biggest piece of advice my dad gave me when I was a young pup. "Don't try to force it, just stand up and the lift will push you off" And that's still true. Don't get all worked up and think you have to push off to clear the lift. That's the point of the ramp in the first place. Just stand up, that's all you have to do!
