You might want to review how a best-first search works. It takes a step based on (for example) an heuristic, but can come back to reconsider that later if it doesn't find a solution. That's why it's a "best-first" not a "best-only" search. This means that backtracking can happen, which you need to take into your analysis.

WebGreedy best-first search is in most cases better than BFS- it depends on the heuristic function and the structure of the problem. If the heuristic function is not good enough it can mislead the algorithm to expand nodes that look promising, but are far from the goal.
