Alright, lets see here. So in terms of combat abilities, I'd say TP Link has the edge here, not just because he's older than WW, but the fact that he has much more combat experience than him via being able to wrestle with a goron, on top of being trained by his ancestor. WW link did get some training, but he got it from an old man who doesn't really have much going for him, as opposed to The Hero's Shade, who's OOT Link and MM Link (a link that has a lot more impressive feats under his belt) and TP Link was able to keep up with him on top of learning his abilities on the fly.
In terms of physical strength, TP Link also has the edge here. There's the previously mentioned Goron wrestling feat, him being able to carry a ball and chain around, and even being able to hookshot a giant bird to the ground, while WW Link's feats are being able to drop a ceiling on a lava bug, which was only possible by the dragon on top of the ceiling, as well as wielding a giant hammer.
In terms of better feats, I'd say TP Link also has the edge here. He's able to fight not only Zant in many different form via the different dungeon bosses he fought, but fought and defeated Ganondorf on a one-on-one sword battle. WW Link was only able to beat Ganondorf with the help of Zelda and the light arrows. You can argue that Zelda and Midna helped TP Link, but in the actual one-on-one swordfight, he came out on top, not to mention being able to overpower Ganondorf in raw strength. He's also arguably a better bowman than WW Link since he's able to snipe bokoblins while riding on horseback, and having the hawk eyes, which greatly increases his range.
All-in-All, I'd say TP link would come out on top.
