Can you explain or link, please? Not sure what you are referring too.
Just read through this very forum and you'll find your answer. Bionic has glitches (yep, all phones do) and needs a patch which has been supposedly coming forever. It really should be close, but its not out yet. Some of us are running leaked versions of it, but that's another story.
What it should fix are issues people are having with data dropping, headphone whine, apps randomly disappearing, and some other stuff, as you'll read. Note that not everyone has problems. My phone never had headphone wine and very minimal data drop issues (I've upgraded to the leaked update and its great antenna-wise, but still I personally never had much problem before I did). And to be fair it sounds like the Razr is suffering from very similar problems.
For the disappearing apps phenomenon, you just have to make sure no apps install themselves to your "media area" as some, like games, like to do. You go to Setting>Applications>Manage Apps>Click the Media Area tab, and anything with a checkmark next to it you need to click and then hit "Move to Phone". There, that problem is solved.
In any case I love the bionic. However, if I were deciding what to upgrade to RIGHT NOW as opposed to back in early september, I probably would have waited for the galaxy nexus because having an unlockable bootloader and something that devs can really sink their teeth into is important to me, now that I've gotten a taste of what that can bring to your phone. The bionic has some great dev support right now, don't get me wrong, and actually looks like it will be seeing CM9 and other goodies in due enough time... but that stuff might not even be important to you. Its hard for anyone to advise you because A. everyone has different wants and needs and B. some people you will find are very happy with their bionic, while others are very disappointed.
Sorry there's no easy answer.. but maybe I've at least given you some info that will help you make a good decision for yourself...
