Apart from red-blacks being easier to implement.

All operations (insertion, deletion, lookup) seem to have a time complexity of O(log n), in both trees. Is there a certain difference between these operations that I’m missing?

If you google search “red-black” “2-3 tree”, you don’t find any comparison between the two..

I’ve come to understand that red-blacks are generally considered to be the best. (I’ve heard that one of the reasons [EDIT] why red-blacks are faster than AVL trees (same category)[/EDIT] is efficiency in “application to persistent data structures”, because of rebalancing efficiency; but that doesn’t answer my question..)

    I’m not familiar with 2-3 trees, but I am pretty sure that B-Trees are by far the preferred for persistent database/filesystems. Red/Black more often used in memory
