When working with hexes, you quickly realize their edges are a huge pain. They don’t line in a straight line! That makes it impossible to subdivide the grid with a line. You cannot build a big hex out of lots of little ones.
Triangles solve that. Squares also do not have that problem. Triangles work better on the surface of a globe than squares though.
I thought so too until I read this https://www.boristhebrave.com/2021/05/23/triangle-grids/ which touched on my biggest gripe with hexagons:

As a finite element method enjoyer, I always regarded triangles as superior because many shapes can be built from them. Triangles are the bestagles?
