I wouldn't say that the T&T rod is better than the GLX, not would I say that the GLX is better than the T&T. They are very close is recovery rate, power, tip strength, and action; however, the T&T has a flex profile that is a bit more parabolic than the very linear flex profile of the GLX. These are my two favorite rod makes and I own and use models made of both T&T and GLX rods. One is not better than the other, they have a slightly different "feel" because of the different flex profile.
The T&T has a mid-section which is slightly more flexible than the GLX, which is why it has more of a parabolic flex profile and the GLX a more linear flex profile. I'd venture to say that if a person likes T&T rods, he will also like the GLX rods and vice versa. The people you have heard from that T&T and GLX are are very much alike are accurate in their assessment.
Since you live in Loop country, you ought to take a look at the Loop Green Series because they are very similar to the T&T and GLX rods. And since Loop is a "home company", they will undoubtedly be lower priced than the T&T or GLX.
