A lot will depend on what type of music you want to play. A few things to pay attention to... Is the intonation good? Does it stay intonated? How well does it stay in tune? Does everything work properly on it? Is there a lot of fret wear? Is the neck warped/twisted? Do all the notes fret clearly? What kind of shape is the nut in? Is there any rust or corrosion on any of the hardware? Does it sound and play well for your style of music? Finding out the answere to these question will greatly help you make your decision, and help us give you better advice.

You might want to make a pro's and con's list between the two guitars. I don't believe those guitars are worth very much, but I could be wrong. Usually, if a guitar has a decent value, you can find more info on it than what you can on the UC-3.
