As a user of Sierra for a while, I've not encountered any issues and that's because whenever I "upgrade" I just do a complete reinstall of the OS from scratch. I only noticed after having Wi-Fi troubles in Yosemite, and doing a fresh install of Yosemite actually eradicated the slow, disconnecting wireless along with terrible battery life. I ended up getting back my usual 9 hours, from the initial 4 hours I had after the upgrade.
The reason behind not upgrading to High Sierra is pretty much this: What if it causes issues for me?
I mean, I was fine with Mavericks before Sierra and Yosemite. I only went Sierra after actually preferring that over Mavericks.
