I am looking to get a new bike, but only want to spend around $500. I’ve looked a little at the Specialized Hardrock and Fuji Nevada. What is the best bang for my bucks and why?

If you say one over the other because of specific components, which components exactly are better and why?

Thanks!!
BTW… I’m ~5′9″ tall and ~200 lbs., and have been told that a 17″ frame is about right for me.
