I have spent a non-trivial amount of time going through SMUs and testing 
upgrades. Considering that Cisco do not do testing of SMUs in any-to-any 
configuration, I am a big proponent of SPs, where the SP is properly 
tested, and contains all rollup bug fixes.

I've run into issues where two SMUs didn't work together, and when I 
complained I received the answer that this was never tested. I've also run 
into issues where all SMUs couldn't be applied together, requiring two 
reboots to apply all SMUs.

So... again, big proponent of properly tested SRs instead of SMU-hell.
