I would certainly go with option 2, and I would ask that if you have the space for a 2.1 system, why in the world you would even consider a soundbar at all? Soundbars are an improvement on TV speakers, but rarely are as good as a proper setup using 5.1 separate speakers with added speakers for Atmos if desired. I would strive for the best quality for surround sound and stereo if possible, which a soundbar won't really do justice for, even if it is an improvement on the TV speakers. But, obviously up to you.
