recursion v/s iteration

which one is better: recursive merge sort or iterative merge sort?
recursions normally take lot of time

recursions can take lots of time ,but i have checked it on geeksforgeeks.com and it shows that iterative and recursive merge sorts both have the same time complexity of O(nlogn).so i guess it is just your doubt…anyways if notice anything else please inform me

i also think recursive and iterative take some time…only thing is recursive easy to code and it use stack memory on function call…recursive is not fast it is a way to think about solution and keep code neet…if anything wrong please inform me…
