I don't agree. The most important aspect is that ENTJ's will argue based on empirical evidence and practical applications. They are likely to be convinced more by facts than anything. As a Ti dominant you will gain points by using this.
I don't think Ti has an edge over Te. Both are necessary in science and philosophy and I think none have an absolute advantage over the other.
What I meant by the claim that Ti has an edge over Te is that it is more germane to the quintissence of 'Thinking'. Or in colloquial terms, it is more T than Te.
Jung inherited the notion from Schopenhauer that the essence of mind is unconscious. There is no distinction between the conscious and the unconscious--all of mind is unconscious, conscious is only an external manifestation of the unconscious.
Jung also argued that Introverts are closer in tune with their unconscious. All functions stem from the mind. We equate the mind with the unconscious. Thus the closer a function is to the mind/unconscious, the stronger it is.
Te and Ti derive from the same quintissence--Thinking. Introverted Thinking is more of a 'Thinking' function, because it is closer to the unconscious element of 'Thinking'.

You seem to be saying that by external standards, it is hard to tell which is superior. As we see Te tends to be more successful in science, and Ti in philosophy. Both tend to be successful in intellectual endeavors, and it is hard to tell which one has an edge. That is a claim that I do not attempt to refute.

My point is, as aforementioned, is that ITPs have a stronger 'T'.
We tend to associate tough-mindedness and forcefulness of opinion with a highly developed Thinking faculty. Because ITPs are more 'T' than ETJs, their mindset tends to be tougher, and therefore more likely to emerge victorious in the head-on clash.
Thus, whilst an ENTJ may express more confidence in himself being logical, the ITP will actually be the one more confident of the two because his thinking preferrence is stronger. My point was that the ITP need not be intimidated by ENTJ's confidence in his reasoning, as he actually has more of this element himself.
