I purchased BOTH at full price (Beejive for $15 and IM+ for $10, thanks for whoever gave me that iTunes giftcard, lol). Me personally, I prefer IM+, I just like the UI better on the iPhone, like that it can stay logged in for 3 days (push technology), just like the way it looks, and it takes care of all of my IM needs (talking to all of my friends on AIM, Yahoo and Facebook). I never liked Beejive. I deleted it because I wasn't using it, but I know millions of people love it. IM+ for $1.99 is a no brainer, really, you can't lose. And Beejive for $10 is a good deal if you don't mind the price. My suggestion, try IM+ for $2, if you like or love it, you don't need to spend the $10 on Beejive.
