This is a classic struggle on Pinside.
Data East Games were inferior to W/B in almost every way; Art, sound, layout, sound, rules, mechanics, sound, art, parts etc. EDIT: SOUND
Before some old fogey waddles in here let me say yes they had Stereo, but THEY WORST sound ever so it cancels it out.
Back in the day when all these games were new, NO ONE that knew anything aboot pinball or played all the time thought DE were as good as W/B....NO ONE. Of course now that new people rush in, prices go up, all that's left are shitty DE games (poor peoples games) for people to buy, and they buy them, like them, and think if you don't like them you a sheep or snob.
This is the same thinking on Pinball 2000 which is just another option to buy and cute now, but at the time it was the end of the pinball biz and we weren't happy.
Of course there are good DE games, of course they come with good good art, layouts (thanks PL), rules etc...but they are certain(t)ly under B/W.
But look at the bright side...they're way better than 90s Gottlieb games so there's always a good side.
