Crystal vs DMS4 for Slimline PS2

Hey guys,
I’m going to buy a new slim PS2 in the next following weeks and I know there aren’t a great deal of mod chips available that are compatible with the new PS2s.
I do know that the DMS4 and new Crystal chips are compatible with the slim PS2s and i was just wondering if anyone at the moment is using these chip/s or knows anything that may help me decide which chip I should get installed, or information on which is the better chip.
Cheers.

the crystal is not intended for backup play, it only plays homebrew software, also the dms4 is a bit overkill if you ask me, but a good chip nonetheless.

I suggest you go to ps2newz.net and read there, lost of info on this subject.
