Logitech Z623 or Samsung HW-M360/ZA?

Which is the best from between both systems ? Trying to buy one from the two but confused..The logitech z623 has a bluetooth adapter too however is it only for 1 speaker or all 2 speakers and the woofer too if I played music on my phone via bluetooth! The samsung comes with Bluetooth however I wanna know which is the better from the systems mentioned above! :)
