Mid 2012 MBP retina - which OS to upgrade to?

[Macinthelou]

I have a mid-2012 MBP Retina (2.6 GHz i7 processor with 16 GB RAM) still running the original installed OS 10.8.5. I am thinking about doing a clean wipe/reformat while upgrading the OS. Any reason NOT to upgrade to OS 10.12 Sierra? (i.e. should I worry about any performance issues with the latest OS)?

Thanks!

Sierra will work absolutely fine on your machine; maybe even a little smoother than Mountain Lion. You still have a very capable computer so you needn't be concerned about performance on the latest OS.

Same model as mine, apart from a few issues with Mavericks, I've upgraded each release with no issues apart from incompatible 3rd party software for a few weeks after each release. Sierra runs at least as well as any OS I've had on it and I'm now on 10.12.4 beta with no issues (for me) at all.
