As much as it pains me to say it (I'm a HUGE Star Wars fan), Star Trek absolutely destroys Star Wars. The layout is far superior, and the code actually makes sense for the layout. Star Wars layers and stacks modes, hurry ups, progress towards modes, multipliers, action button instances, and more all while throwing a game at you that's always at breakneck speed. It doesn't make sense to put such heavily layered code on a game that never gives you a chance to make measured actions.
Star Wars somehow feels like there are things missing while still feeling like there's too much going on at the same time; and it makes for a frustrating experience. When playing Star Wars, it feels more like you're just surviving through three balls. It's not that the game is hard, because it's not that difficult to progress through, but it's just hyper speed all the time on the physical end while the code is asking you to make deliberate decisions. It really makes no sense.
Star Trek, on the other hand, has a fantastic layout that tempers its speed enough that you can actually look at the game's indicators and properly play modes, hurry ups, and sequences that involve the action button. It can also get very fast, but it isn't always full throttle. There is WAY MORE strategy in approaching the different modes and multiballs in Star Trek than Star Wars as well. It's just all around better code and a better layout. They are so much more of a cohesive experience and feed off one another rather than clash and fight against each other like on Star Wars.
Can you enjoy Star Wars? Sure. I can see how some people might like that frantic madness, but I would say that Star Trek is objectively a better pinball machine. It feels so much better planned out and so much more carefully crafted on both the physical and software sides of things.
