Another vote for DP.
Every shot in that game is fun and never seems to get “old”, the code is deep and interesting, the game has possibly the best video content, callouts, and sense of humor of any Stern to date, and of course the art package and lighting speaks for itself.
My only (completely subjective) criticism is that they got a little lazy and used too many colorless inserts in mid-playfield, but the Pin Monk “brackets” fix the issue (the only mod I’d bother with for this game).
Wonka is no slouch either (and has superior build quality, assuming the playfield is OK), it just doesn’t punch nearly as high as DP for me.
