There is no reason to even argue. Sterns dont hold a candle to a decent Williams.
Sterns low-budget corner cutting designs are boring, generic, and useless.
As mentioned, their software sucks. Its nowhere near the Williams quality level,
most likely due to cost & corner cutting.
The sound quality is crud, And annoying, due to random voiceovers that overlap
each other without modal reason.
Flipper feel is crud. There flipper mechanism hits in such a way that is not
dampened, and makes a metallic clank sound. The vibrations reverberate
all through the game, and right into your hands/wrists.
The Williams flippers are much more grounded, and sound & feel more like two
wood blocks smacking together. The sound less noisy, is much more pleasing,
and theres much less vibrations transferred to the players hands/wrists. Pressing a
flipper on a stern, is simular to removing the glass on a williams, and then hitting the
flipper... but even worse.
The Playfields on Sterns are inferior. Generic photoshop pics and low-resolution
inkjet printing. Its well known that Inkjects are far inferior to Screen printing.
The Stern fields themselves, are less durable. They are soft, and dimple way too
easily. The way the ball reacts on them will be different too.
Artistry - Stern has none. No real art on the Backglass, sideart, playfield, nor theme.
Lifeless. Boring. Generic.
Poor Gameplay - Sterns are so rushed, they often have major gamplay flaws.. such
as merciless side dumps, awful useless toys like the cannonball chamber, poor
ball flow, things that slow the game down too much... such as the path of the dead,
and much more.
