In case you are unable to decide one way or another, try thinking about it from a different perspective. Remove the constant threat of layoffs from your consideration and ask yourself if you still enjoy your job. It might sound simple, but it certainly helped me decide to stay.
Layoffs are a threat everywhere, but I actually still like my job. So I'm gonna ride it out. Other people will probably make a different choice but the end result is the same - you are moving on from a stalemate position.
