I too have Sierra installed on a spare drive. Haven't really pushed it really hard only running MS Office 2011 apps, Firefox, Thunderbird, Preview, TurboTax 2016, and may be Safari. The one thing I notice on my mid 2012 MBP with 8GB of Ram and platter HD is Activity Monitor shows Swap Used values I've Never seen in El Cap. For now I'm staying with El Cap, Sierra really doesn't seem to offer me personally anything I need.
