Its horses for courses, you fly the profile required for what you want to achieve, be it obstacles, cooling, SOPs, etc.
One thing you will find is different instructors will have different ways of doing things, glaring at you if you do them any differently. It does not mean to say what you are doing is wrong, just not what they are used to. Once you get more experienced and get pulled up on something you will actually be able to turn round and explain WHY you are doing it that manner and you may find that they actually learn something!
