In case you forgot the differences, here's an image showing the three side-by-side:
SSB4 Link borrows heavily from TP Link, more than any other incarnation in the series. The vibrancy of his clothing, as Sakurai said in the Developer Direct when speaking of Mario, was to focus on the visual sharpness. His face is different from Brawl's Link, possessing sharper features—but look at all his gear. The Master Sword is definitely the TP-style silver versus SS's blue, the Hylian Shield is TP-style (it has the metal frame around the Triforce which is clasped by ornate markings, along with those metal shapes at the base of the bird, whereas SS Hylian Shield has neither); his boots possess the same markings and are slender and longer—and the most obvious: he doesn't have SS Link's lofty pants. His clothing is much more tight-fitted than SS Link's. The tail of his hat even has that stitched on extension that is characteristic of TP Link. Furthermore, his left arm has the brown leather armguard, while SS Link simply had a blue bracer. He has the same collar stitching as TP Link and a rectangular belt-buckle, not a hexagonal one. His chainmail is also gold-tinted, not obviously silver.
I hope you can see the similarities and differences. There's no denying this Link references TP Link more than any other.
