Elevated track

Question: Do you favor elevated track (trestles? built upper levels? separate layout above?) or never going up and down and always expanding on the same level.

The disadvantages I find with my elevated trestle track is no variation is possible because the trestles need to be attached so firmly to the base (this is O and O-27 gauge). Once the elevated ine was secured, it is tight and wired and runs strong, but it can hardly be moved, and it also interferes with moving the lower track (two lines, intersecting).

Any thoughts?

I am thinking of having an entire O-27 elevated and multi-level layout in, running INSIDE a new standard O-gauge layout.
