If low poly characters (say 6000 and down) do what you want them to do, then use them by all means.

If high poly characters (120k to 400k) are what you want, use them.

I use characters ranging from about 15k to about 200k+. All of them have a use, but the 60k to 200k+ ones get used the most for what I do.

Many of todays video games engines support fairly high poly counts now, so a 100k+ character for cut scenes and 10 to 50k for in game action is not asking that much. Obviously if you need to have lots of characters on the screen in a game at the same time they need to be much lower polycounts. Poser 64 bit doesn't really care what poly level they are because nothing is interactively rendered like in a video game.

Some people will tell you that extra polygons in a mesh are just pollution. But that is not entirely the case. If it were the case, there would be lots of elongated polygons on many  characters. Wireframes normally have a certain average polygon size thruout the mesh, which will add loops to keep things that way. Avoiding triangles and 5+ pointers in joints also adds more loops. Depending on how long a loop is, it can add a lot of polygons to the mesh. The denser the mesh, the more it will add.

There is nothing wrong with using low poly meshes, just as there is nothing wrong with using 200k+ ones. It is all a matter of preference, and application.
