I can understand why some people would see Smash TV as the better game.
As a kid, I played Robotron like Once in the arcade. I avoided it because to me, at that time in my life, it looked like crap compared to other games in the same time period. I decided that maybe I was missing out on something, because I had discovered that some poor graphic games actually were very fun. But Robotron gave me about 30 seconds of play... stomping me to bits.. and I was so underwhelmed, and ticked off at the beating.. that I never went back till an adult.
Years later, Smash came out, and I loved it. Funny, fun, and much better graphics than Robotron... and I could tell it was a Robotron remake. The problem with it? It was a quarter muncher. I really despise continue games... partly because they are so cheap with putting you in impossible to survive situations.. just to get more quarters out of you.
Then, as an adult, I was arguing with a guy about Robotron -vs- Smash TV. He INSISTED that Robotron was the superior game. I was shocked... and really couldnt understand it... So I hunted down an original machine, and began pumping quarters into it.
After about 10-15 games, I started to get the ability to survive through several levels... and started to get the compulsion, but still not convinced. After 20-30 games, I was finally getting past level 9... a barrier that seemed impossible at first. After maybe 10 to 20 more games, I was getting good... and had marathon streaks up to levels over 20. Somewhere around this point, I became a true Believer. I was also seriously addicted. I spend about 5 hrs playing Robtron (only) that day... only really stopping, because the place was closing up for the night!
Robotron kicks Smashes butt in every way that matters most. The game is hard, but its also relatively fair... unlike Smash. Every Nth level in Robotron, you have a chance to get extra men on the Brain stages. Smash needs more quarters for extra men. Smash is relatively Slow compared to Robotron. Robotron needs lightning quick reactions... at every moment of play. It makes gets your adrenalin pumping, and your heart racing. Smash is much more leisurely... or all the sudden it gets impossibly cheap... so it just ticks you off. Smash often puts you in an empty room, Robotron Always puts you in the middle of robot-hell, many times with only a few pixels between life and death.
Smash TV is Elevator Music.
Robotron is Heavy Metal.
Sadly, I have no access to an original machine. The guy decided to get a multi-willaims cabinet... which had some crappy Happ Comps on it. I tried it a few times, and couldnt do Squat with it.. due to the lack of control that the original wico 8ways gave. I walked away in disgust.
I learned the beauty of well adjusted Wico leaf sticks. Not just for Robotron.. but for many classics. Robotron just sticks out in the argument... because its one of the games that is so intense, and needing those sticks to merely survive. Other less intense games can play OK with other sticks.. but they still will at minimum, Feel better, with leaf sticks.
