That is a tough call, with #1 being somewhat better. It is even better if you can pull the love seat forward of the speakers by a foot or so. IMO, a center speaker and second subwoofer might be a better investment, instead of the surround speakers.
If this is to add speakers for 5.1, they are called 'side surrounds'. When you go from 5.1 to 7.1 you are adding 'rear surrounds'
