Yeah, what’s “best” depends a lot on how you use it. This Zojirushi seems more like a vacuum flask that you can also drink out of. Great for throwing in your pack and going for a hike, or leaving in the car all day while you ski.
I just want a mug that I can drink out of like a regular mug. I don’t want to flip a lid or push a button just to have a sip of coffee.
