Need some help choosing

[mrandyday]

I know that this kind of thread is very repetitive but I want to clear my doubts before getting a phone that I won't be very pleased with. So I thought you guys might help me to get this figured it out.
I'm from South America, so the price that I can get is without a contract. My budget is around 450$ and my first choices are the nexus s and the infuse 4g (I really like the Samsung TouchWiz more than other UI).
I've been reading a lot about those phones specs but I want you to recommend me based on your personal experiences .
Which should I get?
(or if you want, you can recommend me another phone)
tnx

If I remember correctly, infuse is something similar to Galaxy S1 right? If that's correct the only diff would probably be the additional elements touchwiz brings. However the Nexus S will be getting ICS for sure and early, and with it some features originally found only in Sense or TW, so I'd pick Nexus.
