I completely second getting a bar table. They are just so much easier and more forgiving to shoot. Games are quick and if your playing with people of different levels it makes things so much more enjoyable. Those bar tables are tanks and if you have the felt and bumpers redone they play beautiful. Buddy of mine has a beautiful official 8 ft table in his house and a bar table in the shop, I have probably played a 1000 games on the bar table and a handful on the far more expensive official table.

I don't know the specifications on the size difference, but a bar tables has slightly bigger pockets that are more square, standard tables the pocket is tighter and curved. I don't know your budget, or what it costs but when my buddy picked up a bar tables, he had a guy come out and replace the felt and bumpers. It was super quick only took an hour or so and now it plays like its brand new. Getting the playing surface restored is trivial.
