why do you keep insist on not relating to price? whenever you mention bose price is a factor since you are spending much more than the speakers are worth.
i've owned plently of logitech systems in the past and they have all sounded good and were reasonably priced. to me bose products sound no better but will cost you at least $100 more. bose is all name. they are far from being "kings of the speaker world".
but, pick what you want. best thing to do is to hear both sets in person and pick which you like more.
