Using recursion to solve problems often simplifies complex tasks by breaking them down into smaller, more manageable subproblems. This approach aligns well with many algorithms, particularly in domains like tree traversals, factorial calculation, and searching. With recursion, a problem can be defined in terms of itself, which helps to express the solution in a more straightforward and elegant manner. This reduction of the problem's complexity can make the code more understandable and easier to maintain, as each recursive call focuses on a simpler instance of the same problem.

While recursion can consume more memory due to function call overhead and the system's call stack, and it is not necessarily faster than iterative solutions, its primary benefit lies in how it effectively simplifies the coding of problems that have inherent recursive structure. This makes it a powerful tool in a programmer's toolkit for certain types of algorithms and problem-solving scenarios.
