MOPs, as you probably know, the grid actually consists of triangles. Those. Despite the fact that you can make polygons with almost any number of sides, in fact they consist of triangles. What does this mean? This means that, because The real surface of the model is formed by the arrangement of triangles, and not of entire polygons, you can get an unexpected result. You create a polygon whose points are not on one plane, but are scattered in three-dimensional space. How exactly this polygon will be broken into triangles, only 3ds Max is known, which can hardly read your thoughts. Triangulation, of course, can be corrected in the tools of the sub-object level Face in Editable Poly, but why? It is easier to do everything from the very beginning, as the renderer sees it. But here there is one nuance. Visually perceive triangles is very difficult. Therefore, for artistic (not technical) reasons, the level of detail of the grid can be reduced to the level of quadrangles, i.e. Quads. In addition, if someone has a personal dislike for the quads😁, it's still easier to work with them, because Polygon modeling tools are sharpened just for them.As for SubDivision, it works at the polygon level, as a result, each extra Edge adds a "fold" to the final grid, and every extra point of the polygon beyond four, carelessly and disproportionately smears the surface, especially when this surface is mapped.In your example, all quads are good. If you really want to compare, the most square one (# 1) is the best, again, for reasons of visual perception😉
Good day. I ask to help or assist with such question. I was engaged in modeling a small Kitbash. And now I faced such a problem. I'm trying to do everything with quadams. And on the curved surface, when you try to do the detailing, there are draws. When smoothing it looks wretched. How to avoid this? What is done is not true?

Yuri, try to manage the mesh the shown way. If you still have wrinkles, then double the number of cylinder segments to "stop " the stretching.
It turned out quite neatly! Once again many thanks for the help.
