Can you share photos of your space? There's really no way to make a judgment call here without context.

I voted for the first table, that is what I would order for my house...I don't know your style. 6 foot diameter dining table will have six to eight dining chairs around it, and many of the bases will make it very difficult to have more than four chairs around... four chairs will look very sparse around a large dining table.

In my professional opinion, the first one with the pedestal base is going to give you the most leg room and the most comfort when seating around the table. The legs are not in the way.

I hope this helps!
