We have just been through that process with our 19 (that we are picking up next week
You know that the standard table has the slider to let the driver side person in, as well as the larger leg posts (requiring bases permanently screwed to the floor), while the hinged table is 8" shorter because without the slider it would difficult to get in. It is basically the same table that is in the back of the 17.
We like that the folding leg is smaller and does not require a base screwed into the floor; it makes for a smooth surface underneath when made up into a bed- easier to stow boxes etc. We're hoping the smaller folding leg leaves us a little more space under the table for our puppy dog's bed.
Reace gave us the option of leaving the passenger side of the tabletop square rather than cut at the same angle as the driver side; this makes for an asymmetrical table but gives a little more area. Since we are losing 8" of tabletop length we decided to go for this.
Some people have said it is easier to set up the dinette bed with the hinged table and smaller leg rather than with the standard size with the larger legs; Tammy said she doesn't find the bigger posts that difficult. If you do get the hinged table they give you an extra piece to fill in the gap that's left because of the smaller table top.
You have to decide you want this change before they begin building because they have to add extra reinforcement where the table joins the wall. They didn't charge us any extra for this modification.
Since there are only the two of us, we were happy to compromise the length of the table for the other advantages. We posted our happy experience with getting this option at http://escapeforum.org/index.php?topic=2238.15

about earlier discussions on the table.
We'd be happy to post some photos of our table next week
