Everyone asks- If آپ were Bella... but i ask -If آپ were Edward..

Bella, probably. Bella is the one for him. The one he'd been searching for so long.

I don't think I would be able to stand stupid Rosalie.

Hahh, good question!
Now, if I'd be Edward, I'd probably choose Bella, because she's the one for him.
But if I'd be just a vampire, and not Edward, I'd choose Alice (and let's say she never met with Jasper)
Now, does this make any sense? :D
