I've owned 9 Stern (still own 8 sold SM but that's a solid title also).
I can't say what's best for you. But for me, I'd strongly recommend Iron Man (or Tron or Met pro) these three are all fantastic. Like I can't choose between them but if I had to I'd probably say IM by tiny bit.
My other suggestions are AcDc premium or Tspp.
I had a pinball party and IM was the most played game.
As Panzer said XMLE is nice value and PotC is still good, I've owned it for 8 years or more and hard for me to let it go.
