DMS4 vs Infinity?

[Cyber Akuma]

Many people used to recommend the DMS4, however, a lot are recently telling me that the infinity is better.

I am wondering, is there any side-to-side comparisin of what features each one has and dosent have? Even the smallest of features....

Mainly, its important to me that the chip will work on a V4, supports the official HDD (I play FFXI on my PS2, I dont want that ability disabled), supports playing PAL games in NTSC (I have a few PAL PS1 games on me, half of which DONT work in emulators >.<) and direct-boots any PS1 or PS2 media. and can use cheat devices like GameShark, Action Replay, and Code Breaker. I know the DMS can do all this, I dont know what the matrix can or cant do.
