I will strongly recommend against the oversize eight footer. Like an eight foot table it is neither fish nor fowl. I would much prefer the seven or the nine over the odd sized table.

This is a regional thing. There was another thread involving this topic last year.
Here where I reside, in North Texas, you walk into a pool hall and the first thing you encounter is the majority of over-sized 8-ft. tables in the facility. If I remember correctly, Central Texas was much the same way.
Now that I've seen the OP's second post where he stated he had room for BOTH tables, then I would definitely recommend the 9-ft. table.
