Don't update El Capitan 10.11.6 on MBP circa 2016?

The only thing I see as a hassle is Google Drive not backing up and syncing, but otherwise I only use my MBP for streaming tennis, internet and MS Office.

Is it worth updating my OS to Sierra? Someone warned me that if I did that, my MBP would run incredibly slower.
