The curve has more memory, and QWERTY Keyboard, but it all depends on your preference. I went straight to the curve, the pearl was too small for me. At times I wish I had it, just for the suretype, but I love my full keyboard.
I have never had a pearl, but i have a curve (8310) and I love it. I dont think it is too large at all. It fits easily in my pocket. I am not sure what features you have my (8310) doesn't have wifi and the video quality while watching You tube videos is not good at all. But I still am completely addicted to my phone! Good luck
I'm having the same problem...i've had a pearl (8130) for about 4 months and am thinking about upgrading to a curve (8830) already. I think I would love it. My main concern is that i'm a busy mom on the go always and carry my pearl in my front pants pocket all the time. I worry the 8830 won't fit. That is really my only worry. Comments on that anyone?
Good luck on your decision and happy berrying.

Best thing to do is head to a store selling the phone you are interested in and ask to see it untethered, so you can see how it feels in your hands and pockets, as well as play with it's features.
There really is no better as far as the phones go, but there is what feels and looks good to you. In my case I'm a QWERTY typer, and found flip/bar phone txting, something I only did when someone else sent me a txt message.
The ONLY way you are going to tell if the size is too big (for you), is to play with one for a few mins/hours.
