i just upgraded from the razr to the hd, and i love the hd, and really really really liked the razr...however, i don't believe an upgrade to the hd would be worth a loss of unlimited data, but if you can upgrade and keep the unlimited data(there is a loophole that would allow you to keep unlimited if you're on a family plan with dumbphones on a line that isnt being upgraded), then i say go for it, and you'll be happy you did...
