Anyone compared 5S5A & 5SG7?

Traxdata released a new firmware for their 24x drive (5SG7) - it is a modified LiteOn 24102B 5S5A - but there are more differences as the ident-string only - so I wonder has anyone compared the firmwares (write quality, match more media?)?
There is a new firmware ZSG8 for the 401248plus, but it is simple 40125S ZS0P with different ident-strings (no more differences).
