they are both rock solid games. with the nod of toughness to W/B. DE has plastic popbumper bodies and other things that make it feel clunky and power supply needs to be rebuilt if it has not already and fuse clips are the enemy of that and all data east games.
Whereas WB games have the best mechs and flippers in the biz. But some games like popeye leave people with a bad taste sometimes. Not all games are TAF,AFM or MM. lol
I like popeye and give the nod to it for your choice by quite a margin. RnB is fun but gets old relatively quick. If you like TSPP my real recommendation is family guy or shrek.
Family guy being the better game by far! I have both fgy and tspp , neither are leaving. Had RnB and sold it still looking for a popeye to complete my superpin collection.
Good luck and play both and buy what makes you feel happy and warm inside. Forget everyone else.
