Bottom-up solutions are often faster in the worst case, in absolute terms (not asymptotic complexity) because memoization is a relatively expensive operation. Top-down solutions are often faster in best or special cases, because they evaluate only the subproblems that are needed for each problem instance.

Which approach is better top-down or bottom-up?
While a bottom-up approach allows decisions to be made by the same people who are working directly on a project, the top-down style of management creates distance between that team and decision-makers.
