It seems the common reason for not getting an S-line and going with the SE is due to the firm suspension.

It's therefore surprising that so few go for what I believe is the best of both worlds i.e. an S-line with dynamic suspension. Perhaps it's the £600(odd) cost however it gives a car that's multiple cars in one.

I guess as long as you make the choice you're happy with then it doesn't matter a jot.
