Simplifying meshes question

[Lurok91]

What's best way to remove/reduce number of faces in a mesh but still keep shape of object?    Is it best to do by face, or by vertices?

Max has a Optimis modifier, this is a quick way of doing it though I have only used this in charactor heads so far.

Using that modifier produces mixed results.  Use it with caution, cause it can actually deform a shape.

...and mess up mapping too.

I suppose it could at that, yes.
