Home versions aren't at all the same machine.
Nothing like the same machine at all.
They may share some graphic and sound elements, there may be some 'inspiration' in the ruleset of a home version, but it really is a completely different machine.
I think of it like this:
When Stern contracts with a pinball designer, they ask for a 'Premium' pinball experience. Then the art team gives it a different art package, adds a few things like better speakers, headphone jacks, etc... and a tag that says 243 of 1000 ever made and calls those machines 'LE'. Then for the operators, they try to subtract $1500 of stuff and still keep the machine playable for the 'Pro'.
Sometimes they cut too deep and the Pro really feels as though it is lacking something. Sometimes the Pro ends up having a 'feel' to the game that is quite different than the Premium. Sometimes the Pro is actually more fun than the Premium (fewer ramps/toys end up being a faster layout!).
The 'Pin' machines are a completely different type of design. They try to re-use a known good whiteboard pinball for the layout, and it's just a matter of skinning it with artwork and adapting the graphics/sounds to what is already pre-determined.
I actually like the 'Pin' pinballs. They are simple and fun. They are nothing like coin-op pinball machines, and should be considered separately, in their own category.
