From that list, I'll suggest W810i. It's been arround for quite some time now, and has alot of moddifications which you can apply. I'd suggest you check out:
http://www.mobileburn.com or http://www.mobile-review for a Review or cNet. Use http://www.esato.com to compare the three handsets
Although you didn't list it, I would suggest W850i (3G) or W830i(non3G but otherwise the same as 850). I have switched alot of phones, and after I bough W830i I never had to change my phone again. I think personally it's a perfect phone. Some people do complain about the button placement on the set, but I don't find any difficulty using it.
