Thanks for the replies! My first MacBook. I was worried upgrading might slow it down.
If you had a spinning drive or 4GB of memory I would be more cautious, but with and SSD and 16GB that thing will run High Sierra great.
Fresh install is recommended if you got the machine from somewhere else.
Either Sierra or High Sierra, although it would help to know what software and what versions of that software you are running. Sierra is a little more friendly to old versions of software than High Sierra.
If that's all you're running, then High Sierra is fine. If you were running say an older version of MS Office or Photoshop, I might recommend Sierra.Thanks for the reply. The computer was running ElCapitan. So far I've deleted pages, keynote and numbers. They reinstalled fine.

I mention these cuz if you're going to do a clean install, you may as well upgrade the OS as well.
