First, you need to define what "always use another window" means.  What if
the current frame is divided into so many windows (or is itself so small)
that no splitting can occur because of the minimum window size variables? 
What if the current frame is unsplittable (where you shouldn't split it
automatically), or worse is a minibuffer-only frame that you -can't-
split?

If you want to "not leave fewer windows", what you probably want is to
restore the window configuration.  If that's what you want, just do it:
use `current-window-configuration' and `set-window-configuration'.  (There
are a few other useful related functions which can be found with Apropos.)
 If it interests, I have written a small "temporary window configurations"
package which aims to automate that process.

Hope this helps,
