It depends on your budget. The Samsung system has in integrated blu-ray player, which means that the sub-woofer is probably passive. A passive sub doesn't have it's own amplifier so the bass isn't going to give you that nice, deep, discrete, bass tones. An active sub is one that has it's own amplifier and doesn't derive it's power from the blu-ray player. You also need to look at the type of speaker connectors that the unit has. If it's proprietary, you'll have a hard time upgrading the speakers down the road should you choose to do so. Out of the ones you listed, I'd look at the Yamaha. It's wired but wireless can have it's issues. I have a comparable Yamaha receiver and it has plenty of power for us and can handle any type of speakers we choose to add (binding post connectors). If you want a HTiB system, I'd look at Yamaha, Onkyo, and Denon. Most of the entry level systems of the three that I listed have the current audio/video formats so you'll be able to listen to whatever you want, depending on how you set it up.
