Most analytics programs have some quirks that prevent them from being 100% accurate but for the most part (if they've been installed correctly) are good enough to be a useful gauge of how your site is doing.
Its better to just use one analytics program, otherwise its like the man with two watches whos never sure of the correct time!. It will do your head in if you're getting two sets of different results.
One thing to watch for if youre using a GA WordPress plugin is that it doesnt record admin activity on the site, otherwise the visits to your site will be skewed by your own activity (or if you do enable this just be aware that the visits could be your own).
