Confused between magic3.1 and messiah2

[vegitto]

Gamer Experts,

I am modchip installer, I've done 5 magic3 installation and 4 of them were amazing, but I have bad experience with the last one, I asked people here (Australia), and those people give me the same information that messiah2 is not good enough...let me tell you the brief story...
(I thought when i got this problem, it could be overcome by using messiah2, but it's not, and here is the story)

I called my magic3 supplier(installer also) regarding this issue and they told me it is because the PS2 version 7 that I am using, is using version 5 DVD rom (sometime sony does this, they said), because they also had the same experience before, even though they put blue chip, magic3, messiah2 they were not able to make the console booting for all games.. This is their conclusion, what do U think guys??

I called again other supplier(installer also), and they told me magic3 is better than messiah2, as because messiah2 cost a lot more expensive than magic3 and the result is not quite satisfying, and what do U say??

I called just now (installer and supplier), they give me the new thing called magic3.1, they said that messiah2 can not boot DVD 9 definitely (because they've done many installations), only magic3.1 that can boot DVD 9 and all games without any problem. do you think is true??

experts, I am very confused now, and australia so I think european people can help me regarding this issue...so frustrating too...
