Option 2 has more shelving space all down one side with only hanging space on one side of the unit. This option gives you more space for laying clothes down, so if you have piles of t-shirts this might be a good option for you. If you are storing all of your clothing items in your sliding wardrobe then shelving space near the bottom will give you space for your shoes and trainers.
If you are going for a three door sliding door option then there are plenty further options to consider for your wardrobe interior. There are multiple combinations of shelving and hanging options so that you can get the right storage solution for you and your needs. If you are a couple sharing a wardrobe then the three door option is a good choice since you can have one door each with a hanging section and have a shared shelving unit in the middle door.
If you need even more space than this you can go further still and have a four or five door unit which will give you plenty of storage solution options. With this size wardrobe interior you will be able to hang all your clothes in different sections, have plenty of shelving for all your accessories and shoes and extra storage utilising the shelves at the top of the unit.
