We have a stack of two EX4600s that form the core of our network and provided layer 2/3 services. They are currently running Junos 14.1X53-D46.7. Twice a year we upgrade to whatever version of Junos that JTAC recommends according to this article

There are two different versions of Junos recommended for the EX4600, 14.1X53-D47 and 17.1R3-S1. Which one should we choose? I could not find any good explanation of the differences in these two verrions.
