best modchip for ps2 90004

i opened a thread here but i think it's the wrong section : "PS2 Homebrew/Dev & Emu Scene" in the name of "about modding ps2"

when i came to compare between mods, in my local shops, using some model of M7, but some people from the web are saying that M7 is a clone from another chip, and if i wanna use mode it'd better be either of those:
DMS, Crystal Chip, Matrix Infinity Orange/Green Dot

and some other told me to use:
Modbo 4.0

after a little looking, i found this comparison:

Attachment 37189

will that makes M7 much better than the rest above even tho it's a clone from them? or this result is not correct ?

FYI, i dont wanna use FMCB nor HDD, just advise me bout mods or i'll have to skip it and costing myself in buying swap magic+tools

the modbo 4.0 is the way to go i reckon. its a clone of the matrix infinity but a fully functioning clone. back when ps2 was popular i was using them for later model ps2s as they arent compatible with early models. you must have abit of soldering skill to be able to install a mod in that model tho, as there are no via's for the dvd/cd patch lines and must solder directly to ic legs.
heres one ive installed n took a pic of back in the day (tho i removed the hot glue from top of ic as shielding didnt go back on with it there and was only there to keep the wires from moving. not for installing)
