I've used both G1 and the 9700(current phone)
The G1 has a better browser and 3rd party apps hands down. The berry has better hardware IMO in terms of solidness and quality.
Your battery life on the berry is about 4 times better than the G1 (no joke)
Email is much better on the berry The g1 has better youtube playback
