I've got both TSPP & FGY, and while TSPP is ultra deep, I really enjoy both pins about equally.
A FGY adjusted to Family Settings is extremely tame.
The only thing that may or may not be appropriate for young children would be the modes & DMD displays: Sexy Party, Ipecac, Peter's flame-thrower "gas" animations.
Not appropriate in my day of '60s/early to mid '70s sitcoms; but these days, all a kid would have to do is watch one episode of Family Guy or another show and see far worse.
Love Mini Stewie Pinball; hear complaints about interrupting flow but I try to get it every chance I can.
FGY is more uncommon and worth on average about $500 more.
