Comparing these games is inappropriate. The essence is the same, but the approach to the implementation of the gameplay is different. In Plinko, the gain largely depends on the trajectory of the ball, while in the case of Space XY, on the duration of the rocket flight. In relation to each other, both options can be considered as alternative only in the context of recreation. That is, for example, the player is tired of Space XY, he is tired of following the rocket and pressing the buttons. In order to distract himself, he launches Plinko. And he begins to watch the ball every new round. It does not twitch, while it does not wait for a certain coefficient.
“Plinko” is simpler and more interesting
We can say that playing Plinko is somewhat easier compared to Rocket. In all cases, you need to set certain parameters, but in Plinko it is enough to press the button that launches the ball once. After that, you can not even watch his movement. In Space XY, however, observation is a prerequisite if automatic mode is not activated. Failure to do so is fraught with a series of losses and zero balance.
