Depends on taste also.You did not give a price range or if you have amplification.
I have a room about the same dimensions and I have both.To be truthful I love the Bookshelves,but the floorstanders give me more detail they are also 4X's more expensive.
SOmeone mentioned the PSB Goldi and I have NEARs which are in the same league.My NEARs are modified versions of the time they were compared in a side-by-side at Soundstage.
I think you might get a bigger soundstage using Bookshelves in the room your size.
Go and listen to some to see what your taste are.
