The Best feature of the Dms3 is that you can boot certain applications off your ps2 memory card. (Such as PS2 reality media player) The ps2 reality media player allows you to play divx movies and mp3's on your ps2. You can also use this with basically any mod but you have to boot it with a disc. The Flashabilitly of the chip is a nice feature though.

The messiah 2 chip will boot everything that the dms3 does all with no hassle. Basically performs like a unmodded console in the aspect that you put in the game and it boots. With the exception of p21 games which require one extra step.

As far as playin socom online, every chip will be needed to be put in "sleep mode" because the chip is detected. This means you will need to use your original to play this game on-line. Both the DMS3 and the messiah 2 have this feature.

As far as the install, both the DMS3 and the messiah 2 are hard to solder, the solder points are small and there is no room for error. Even though it's going to cost you more money, most installers guarantee their work. Hope this helps.

For you I would recommend the Messiah 2 chip.
