Best phone under $500?

[Scath]

Already used GSMArena's phone finder to look at phones using the 1700mhz frequency band. Worked really well but it may not have every possible option.

------------------
Ones I liked the most: Galaxy Nexus i9250, One S, Sensation 4G, Huawei Ascend P1, Sony Xperia Ion HSPA+, Sony Xperia TX, Galaxy SII Skyrocket.

For the money, the One S and the Galaxy Nexus have both some of the best ratings found anywhere in the world.

Daily I work with graphics, website design, video edit/production, audio edit/production, marketing, social, customer support (internationally via email, Skype, Viber, Phone.), multi tasking in general.

Don't care about battery life I can extend it.

I am on T-Mobile so 3G and up meaning 1700mhz band is required if ATT or other unlocked.

Here's what I need:
4"+ screen
HD resolution over 250ppi
Good Camera
Lots memory
Super Fast
Excellent memory

Why does everyone say it's the best? The camera sucks but I guess I can get a digital with the extra $300 I save rather than buying a quad core phone. I guess I have to get a nexus since everyone swears by it.
