IMO hell yes! I tried pinball fx and to be honest I didn't like how it played, haven't played pinball arcade.
But as a huge pinball fan I can tell you that the williams collection is awesome, lots of tables with individual challenges and high score to beat, great fun and by far the best pinball game I've ever played. Only trouble is it is damn hard to find!

Depends on how long you're willing to wait. Pinball Arcade is promising most (if not all) of the Williams Collection will be covered in upcoming DLC. I hear people rave about this game, so I was looking into it myself. For whatever reason, it isn't showing up on the NA marketplace.
Well it's made by the guys who made pinball arcade so you better off buying the Williams tables in there but the game has pretty spot on physics and Williams tables always are a lot of fun. However if you haven't played these when you were younger you may find some tables in the collection a bit dry compared to the frenzy action of a game like Pinball FX2.
I'm not too thrilled about their usage of the phrase "over the next few years" though. If they mean that literally, I'd kinda rather just get the Williams Collection now from games on demand. Hoping it'll show up for North America soon. I have this bad feeling that it won't.
