These are all essentially clones of each other. Either of the XL units would be the "best multi-effect" in this poll. You could throw a dart and basically have virtually the same capabilities.
For decent quality and a middling price, get a Kurzweil Rumour and a Mangler. Between the two units, you can cover most needs and still be under $1K. Better than any that you have listed IMHO.
