You said 5...Qf6 with out white to move. Which makes your post with less flair and incorrect.
I'm in the 4 .. Bc5 camp, with the follow up 5 .. Qf6. It works out pretty well for me at my club and in tournaments U1800.
5...Qf6 would drop a piece in some variations.
Black can play 5...Qf6
against 5.Nxc6
against 5.Be3
However, Black can not play 5...Qf6 against 5.Nb3.
Which is another popular variation used by white at move 5.

Yes I would agree that 5. Nb3 should not be met by Qf6. Although I've had this played against me 10's of times in slow OTB games. In those cases I've only had 5. Nxc6, Be3 and once c3 played against me. To which I respond Qf6.
If white would ever have played 5. Nb3 I would not have had a prepared responce. I'm guessing I would respond 5 .. Bb6. Maybe I should update my repertoire, thank you.

5Nb3 is nowdays arguably the best response to Bc5, at least leading to fresher positions. Carlsen has used it in one or two games.
