What you do is you download it and find out for yourself.
I'm not saying that to be rude, really. If Verizon is sending an update it's a mandatory update so it will either nag you until you install or just install it anyway.
Here's the thing about updates: I've seen lots of them on many different phones and I know one thing to be certain. You will see more negative comments about any update then you will positive ones. Why? People will complain more then praise. Froyo was loved until the official version came out and all of a sudden people hated it. Most of the time it was simply a case of something else going on (coincidence), user error, or the occasional bad OTA download.
So what I'm trying to say to you is I have used Gingerbread, I enjoyed it. It was not without some issues but that was not an official version. Give it a try and make up your own mine, don't go by peoples opinions in Forums.
