Probably going to regret sticking my nose in this thread but here goes anyway...
Unless I am reading Shuf's posts wrong I think he was merely advocating the practice makes perfect, flying in a manner that the OP advocates is certainly improves your chances of surviving in the MA, but if you are a newer player then it also pays to get down and dirty once in awhile and explore the other methods. In the end it will make the player a more rounded, competent cartoon fighter pilot. One isn't any "better" than the other but if someone stays fast and strictly BnZ-ing then they may be hard pressed to handle situations when the tables are turned which can happen in the MA. Conversely if all a new player is doing is upping a Hurricane, Zero, etc. and the idea is to merge then hold the stick back and fly in circles are also the types that I think are more likely to fall victim to ropes and other maneuvers that the E-fighting planes frequently use because they haven't worked on them. It's all part of the learning process.
The OP had good advice, keeping those things in mind will certainly help someone who's stuck flying alone in the MA's. I am also assuming that he's addressing newer players with the post because I think that most people who have been at this awhile have picked up on a lot of those lessons already. Drawing from my own experience when I started AH I flew the P-51 exclusively and I got to a certain point where I was decent in it, then I let Mathman talk me into flying the F6F and it opened up a whole new part of the game for me. In the end I was a better cartoon fighter pilot because I could take the lessons I learned BnZ-ing in the 51 and combine them with the lessons I learned flying the F6F where I suddenly couldn't count on the things that I used to be able to in the 51.
One way is no better than the other, but I think a player should try both. Who knows what they think is fun may change, but you never know if you don't try.
Please keep in mind that I'm using extremes examples, I think most players probably already mix the two different schools of thought.
