I'd go TWD as it has more to offer in many ways. Both are great pins: hard, intense and fun with a unique take on its style/theme.
For TWD, it's pretty obvious that Prem/LE is the way to go; it has by far the better overall ratings on Pinside by Pinside, simply using the basic numbers. But people are different, so there's merit with the small group who prefer the Pro, especially when budget is important in the pin buying equation.
