For curved meshes I've often noticed that in my desperation to avoid tris, I tend to extrude the mesh in a way which creates these long rectangular quads:
In this case at least, the mesh is all quads, however the edge flow causes loopcutting to be awkward in some places:
I tried creating the same mesh with more even topology, however I found tris unavoidable. Maybe it was because I was starting with the long-quad mesh, but I also found myself using the knife tool for everything..
This makes loopcuts less necessary and easier to place in most cases, though the occasional tri does get in the way.
An annoying thing about the tris are the poles, though they aren't too noticeable in this particular case.
Both techniques seems to have their advantages and their disadvantages:
Which is considered "better", if any? Are there any better workflows for creating even topology with as few tris as possible? Or is there some trick I'm missing altogether?
