Octagon poker table vs Texas HoldEm

What should I consider when choosing between an octagon poker table and a Texas Hold Em style table?

The Mama, The Mama, The Mama, Yeah asked:
I want to buy a poker table or table top for my husband but know very little about the game. Which is better for playing poker at home with “the guys”? The classic poker table or the oblong Texas Hold Em style table- is it a matter of preference or does the shape of the table actually MEAN something?
