I have the larger table without the drawer set. Just one drawer on the left with an insert that clicks in over it when the drawer is pulled out. It is older but the same thing. I love it.
I would opt for the right side additional section over the drawers. I dont know what it is called but I cant tell you how many hundreds of times I have wanted "something" on the right to either put things on or to have a cutting matt/iron on. Like I said, mine is the older one so I cant get the right side attachment.
