The more complex the model, the faster it will be to render as a triangle
mesh compared to an equivalent CSG object.

(With the caveat that if by "triangle models" you mean eg. "a sphere made
up of thousands of triangles", and the CSG object consisting of a very
large amount of such tesselated spheres and other objects, it's not as
clear-cut anymore, as you are substituting each CSG component with
thousands of triangles.)
