I think so.
Countless times the IPSW install has cleared up annoying glitches or improved connectivity, seen better battery performance in the iOS after beta OTA installs. Something about the full reinstall process works wonders.
Yes, I remember your affinity for ISPW installations towards the end of the beta cycles from previous years. š
I have installed it OTA for now (my wife is occupying the MBP tonight) and will see how it goes over the next few days. If I spot something strange, will redo it with IPSW. šļø
