I enjoy playing plinko, i don't feel it like a drain money machine, it only have some bad streaks as any other game.
I feel like plinko is really similar to slots, i know the animation are totally different but the fact that you can get different multipliers for each bet it makes me feel like both games have the same betting logic. And the fact that bets rolls faster than slots is a +1 for plinko.
There has been a time that I always avoided playing Plinko as I always tended to get unlucky which drained my balance. But recently, I have been getting some success with some nice multipliers (x41), so I guess it all depends. It is entertaining to watch where the ball will lend but also frustating when you keep hitting a 0.2x or 0.3x.
