Yes, the priority is on the side of the penalty taker, because if the penalty is taken perfectly, then even the ideal goalkeeper will not be able to make a single save. But even if we discard goalkeepers and analysts, then when evaluating penalty shooters, we will see they have different levels of skill and different levels of psychological stability - which undoubtedly affects the result and cannot be attributed to chance (lottery).
Indeed and that is why those penalty takers who don't think as much are often the best. They have their plan for execution and don't change it halfway towards the ball again. Haaland and Ronaldo are brutal in their execution, they plan and then strike with maximum power. They can fail as everyone else, but they usually don't. There have been several examples in huge games like finals or semi finals when it was obvious that the taker was nervous and then failed. Strong penalties are mostly those when you can see that the taker doesn't care about the goalkeeper. They don't care where the goalkeeper will jump because they decide that the ball is going to hit the corner at the maximum. But a lot of penalty takers are making almost a comedy or entertainment show out of their shots and I hate it.
This is Lewangdowski His execution of the penalty in my opinion is very miserable. And in general it looks like unfair - I think some kind of change should be introduced in the rules so that we do not see these caprine twitches:

The toughest penalty taker in my memory was Chilavert. Everyone knew that he would most likely hit in the center, but he had such a strong shot that it was impossible to reflect it.
