Cisco UCS C220/C240 M4 Firmware - 3.x or 4.x?

Hey folks,

I have a couple of C220 and C240 M4 UCS's that are due for a firmware bump up from 2.x to the latest and greatest, if nothing else than solely to fix Field Notice: FN - 70545 - SSD Will Fail at 40,000 Power-On Hours - BIOS/Firmware Upgrade Recommended before I have a bad time.

Cisco's current starred releases for both models is 3.0(4r) & 4.1(2a), has anyone got any particular reason to pick one version over the other as it looks like both tracks have recent releases?

I'm going to ask TAC for their thoughts of course but I wanted to see if there's any real world experiences people can share
