I have a Dialed In! and love it. I think it's probably Pat Lawlor's best, although I have yet to play Wonka. Here are my thoughts on Dialed In!:

1. A lot of people initially got "hung up" on the theme, but that's because they don't realize it's a disaster theme. The throwbacks to previous Lawlor games is awesome. Making the Whirlwind Combo is fun if you can do it. I've only done it once.
2. It has a deep, but understandable rule set. Each mode is unique in its requirements. They don't get boring and are selectable.
3. Chaos in Quantum City and Armageddon are attainable. I have yet to reach Showdown. So close. Makes me go back for more.
4. Hitting the side ramp and the SIM card hole are two of the most satisfying shots in any game. Collecting SIM cards is crucial to big points. Knowing when to use Big Bang is important. There's some strategy to it.
5. It's a standard body. (I'm not a huge fan of wide body games.)
6. It feels like a 90s game with modern technology.

All JJP games have amazingly beautiful detailed graphics on the UI. I think I notice something new every time I play. The light shows are brilliant.
WOZ is a beautiful game and is on my wish list. The theme, art and lighting can't be beat. The rules are very deep.

I don't think you can go wrong with any of the three. I agree you should play them all before you decide which to get. And don't discount games from other manufacturers. If you can, get a game whose theme and game play you will enjoy for months and/or years. Be prepared for them to multiply.
