Basically, yes. (All but the fit being tighter. That isn't my experience with them at all)
There are Basic pairs, Big T pairs, and Super T pairs as far as the different price point are concerned. Big T has thicker stitching and big details then basic and Super T has bigger stitching then Big T.
(Then there are also many different specialty pairs that are made but those are the basic three 'levels' of TR's)
