Certainly, decisions like that are personal ones. And 15x20 is a fair size room.
You can spend more on Soundbars (Yamaha, etc.) and get even better performance, but certainly unless you are strapped for space or running wires is a big PIA, once you get past soundbars and boxes (Zvox) running close to $500 it makes more sense to put together a small 5.1 system like a Klipsch, DefTech, etc.
Soundbars have been made the bastard child of some audiophiles, which is ironic and hypocritical, since most of them could not imagine having a cheaply made 5 speaker system in place of two quality stereo only speakers.
That's why it may always be a good idea to learn what others think, but not take some of it
too seriously.
