You Vote - Short or Long?

Ok I'm having hair issues.

I should preface this by saying I hate my hair. It'd thin, my natural color is ash (which in my book, isn't even a color!) and it doesn't hold a curl or do anything that I actually want it to do.

A couple of years ago I got fed up and cut it off:

It actually looked somewhat like a style. Kinda.

This is what it looks like now:

Now it's long again.

So should I keep it long or cut it back off? Which looks better to you? I have an appt next Tuesday so I've got to make up my mind!
