Depends on what's important, if'n you ask me. I've been on a tight budget and decided to fly past Panama, which I had no interest in, and get to Colombia, which I did have interest in. Thanks for the comment, though. I can see we are fast becoming great friends.
Mendoza, by the way, is a lovely little town in the middle of the desert with great tree lined boulevards, reece is right about this...but it is a little sleepy. I wouldn't budget a ton of time there, unless you are really into wine.
What I would suggest, if you dig hiking and some of the most beautiful scenery I have ever seen, is the small community just before the border to Chile. I spent a couple of days there hiking around and gawking at the beauty of the Andes. This place is just an hour, or maybe two, west of Mendoza.
