Matrix Infinity and DMS3

[complexstatement]

Hey, I know theres another post up with this topic, but it didnt help me at all, Ive heard Matrix Infinity is a much better choice over the DMS3, but im seeing so many posts on problems with the Matrix Infinity, that im having doubts, im living in Brasil, and im going to mod it next week, when i get the cash, and its 140$ to mod, service + modchip, so im thinking really hard on what chip to get, but its stressin me out, so im hoping this post will make my decision for me. So what is it guys... Matrix Infinity or DMS3????
