which version of android 6 ?!

hi
I've these 2 files;

XT1540_OSPREY_RETCA_6.0_MPI24.65-25.1_cid14_subsidy-DEFAULT_CFC.xml.zip
size:884MB date:2016-3-8
XT1540_OSPREY_RETCA_6.0_MPI24.65-25_cid14_subsidy-DEFAULT_CFC.xml.zip
size:670MB date:2016-3-25

1st of is older but bigger and 25.1 in its file name
but
the 2nd 1 is newer by its date and only 670mb with 25 in its file name

I'm confused, which 1 is better and why?
thanks
