Ok, another blackberry vs blackberry question?? Which is better to txt on?

Bold 9700 or Curve 9800? Which is better to text on? The bb curve 8900 or the bb bold 9700?? I noticed that the bold has flatter keys, and the curves are more spread apart. So what do you think? I'm trying to decide on a new phone here..
I meant curve 8900, sry
