That seems to suggest to me that 15.5S is focusing heavily on bug fixes than features, so 15.5S would likely be the obvious choice.

Can’t say things seem any more stable with the newer releases as we just tried to start a program to upgrade to the recommended 15.5S and immediately hit an issue with npm_main process pegging the CPU cycles if you have copper SFP’s installed in any state other than UP. This issue is also present in the latest 15.6S. This occurs with both Cisco OEM and Flexoptics SFP’s across various types (GLC-T and GLC-TE).

TAC case open and escalated to BU, but this has put all thoughts on upgrades on hold for us until this is resolved.
