With brand new trains, that smells and feels premium, leather sits with plenty of room for you and a table that you can easily fit a computer on(if you dont have a monster).
You only have to bring an id woth you on the train and they usually only ask for your name, or not at all! I have sleept through many trips. With cheaper, faster and more comfy trains than SJ trains, it not that hard to choose. You also have the ability to upgrade to a Plus ticket which always includes a free seat next to you, a meal, tea/coffee served to your seat.
It might not be the fastest (although you don't have to travel from the airport) but I will continue to enjoy the fantastic service that is MTR Express!
