Hi, is their any significant benifits of having a messiah 2 installed in a ps2 instead of an original messiah chip?

yes, it uses less power from the ps2 and u have the ability to turn the chip off. nothing much its just to support more ps2 console versions really -
Boring technical waffle coming up...
The real difference between the Messiah 1 and 2 is actually that the M1 has its own on-board crystal for the IC clock signal, whereas the M2 takes a suitable clock signal from the PS2. This makes the M2 cheaper to manufacture, but much fussier about poor installs and interference within the console itself - the correct positioning and length of the clock wire is the most important part of an M2 install.
As far as boot strategy and bios patching goes, there is no difference to the end user between the M1 and M2 code. It's proof of what a seriously precise bit of coding it is that the M1 never had even had an issue with booting DVD9 games, when the Magic series (and clones) had nightmares with this long afterwards.
As for power drain, both the M1 and M2 use 3.3v feeds - the M1 may use a fractionally minute bit more power, but you could in theory have 10 different mods of this kind drawing power before the 3.3v feed they use started to suffer - they really use almost nothing, as shown in the data sheets for the Actel devices they use. The worst for power drain is again those horrible, budget Magics. The old Magic 2 used a huge IC, like the old Dreamcast mods - if you could manage to actually squeeze it in under the motherboard shielding, it was pretty much guaranteed to overheat anyway, it drew a ridiculous amount of power - the old modworld forums were full of pissed off customers moaning about their fried PS2 motherboards after using Magic 2 chips - funny, really, because most of the places those chips were sold also offered M1 chips for only about ?5 or ?6 more...
