Near-zero difference in boot times. For standard Windows applications read times are HEAVILY used so the 850 would have a SLIGHT edge. The real world difference is pretty much completely unnoticeable. Get whichever one is cheaper.
The pc is basically running all the time and I put it in sleep mode when not in usage so boot time won’t make much difference it’s programs and such my games and adobe files will be on separate drives so the 850/860 is just os and programs
