I find Plinko a rather boring game. In fact, all casino and online casino games are just mathematical probabilities, which are later displayed by the gambling game interface. But I really find Plinko very boring, because you just need to watch the ball or chip (depending on the interface).
Every game is essentially the same, they are all EV- game and the willingness to bust your money any of the game does not necessarily need to be boring, there is dice, slots, plinko, crash and so many other games for that. They differ only on the house edge by a certain fraction and the animation.
I think that slots look more exciting, and if you want to know your chances of winning, then it is better to go play roulette. At least there the chances of winning are clearly visible.
Slots tend to be more vivid and colour filled to keep the players addictively thumping the bet button and forget about their balance or the time of the day. Slots come faster than plinko too so I can understand your preference here.
