Rem is great. It allows uniform scaling of all UI elements under a parent along with them font size.

Rem is great. px work well. Both can work and not work for different reasons. The extremes on this issue remind me of spaces vs tabs.
Where is this used? If a user wants to make everything larger then they can use zoom in a browser that works with any units (except for vx, vh, vmin, vmax that break zoom).
Designers or developers.
