Ok, I have been using Go SMS Pro for a day or two now and, for the most part, I like it.
One thing that somewhat bugs me is that there are not many conversation style options. I like to change my style up a bit from time to time and only have to options for this. I miss being able to choose between a bunch like in Handcent. Handcent has traditional Android style (boxed), iOS bubble style, Blackberry style, and more.
Another thing that I am having a hard time getting used to is the way the sent and received messages are displayed in the conversation. I'm very used to sent messages being on the left and received messages being on the right. This is the way the default messaging app and Handcent (and even Chomp SMS if I remember correctly) display the messages. It's not a big deal, but it is hard to get used to.
One other thing that I have noticed with Go SMS Pro is that LauncherPro Plus doesn't show the new message count on the dock. It shows the new message count on the dock with the stock messaging app and Handcent, but not with Go SMS Pro. The problem with this is that sometimes I am using certain apps that are RAM intensive (mostly games, but sometimes other apps as well) and I don't receive the notification of the new message. I still receive the message, just not the sound notification or the notification in the notification bar. When I back out of the app, I can easily tell if I have a new message by looking on the dock to see the new message count. Since Go SMS Pro doesn't do this, I worry that I may miss an important message. So far, I have not been using a RAM intensive app and receiving a text at the same time, but it is only a matter of time before it happens.
Other than all of that, this one does seem to be a little quicker than Handcent and has much of the same customization options as Handcent. Some of which I really like are the ability to change the font, font color, backgrounds, background colors, etc. Also, My girlfriend sent and forwarded me a few MMS messages last night and they downloaded just fine. I'm not sure if that is because I have just recently rebooted my phone to make a MetaMorph change or not. Also, I can't help but wonder if it may have anything to do with how long my phone has been on without a reboot. Either way, it worked last night, whereas Handcent wasn't downloading MMS.
Woodyman, thank you very much for the suggestions! I am liking Go SMS Pro and plan to continue using it. I'll give it a few more days before I completely uninstall Handcent, just in case this app decides that it doesn't want to play nicely anymore. But, none the less, thank you!
