Which is better between Blackberry Essex, Tour, Bold, Curve 9320?

[imm4n_cool]

I am planning to change my cellphone. Which is better between Blackberry 9650 (Essex), 9630 (Tour), 9000 (Bold), and 9320 (Curve)?

I need to know about battery life, keypad, browser and how fast the UI, and how long you use 4 series I mentioned above (for durability).

I would love to get answers based on personal experience. But not please describe the good and the minus from each series.
