Most stable 10.3.1 version for Q10 with Sachesi update?

I haven't recieved the update for my Q10 SQN100-5 and I want to load it using Sachesi. I haven't used it before and I want to be sure that I load the correct version. When I plug in the phone, Sachesi shows me this:

Update 10.3.0.908 available for SQW 100-1!
OS: 10.3.0.1418 Radio: 10.3.0.1419

A user told me that his Q10 runs the best on the 1052 version of the OS, and I don't know if I should load that one or the 1418 shown by Sachesi.
