Personally I'd have to go with Panasonic. I have a Panasonic telephone and mini system and both have great sound and work flawlessly (EDIT: Before my family got me the Panasonic mini system, they compared the sound quality to a Sony of similar price and quality and unaminously agreed that the Panasonic was better). Plus we have a Panasonic microwave from the 1980s that still works almost as good as the day we got it. Sony imo comes in at a close second. Unlike many, I don't think Sony is as bad as some say and I have no reason to hate them. In fact, many of their products do beat out Panasonic's (their MP3-CD players are MUCH better than Panasonic's, at least for this year). But for the most part, for every Sony product out there, you can find a Panasonic one with better quality for about the same price..
