I don't tend to judge my liking of a certain link on how they look. I think that both of the are really fun to use in their respective games, because of the different things you can do with your sword, but I really think that TP Link has an edge.
With WW Link, I think that the swordplay felt the smoothest and easiest to do. You learn very early on about the various sword techniques, which really aren't all that different from say, OoT, but the almighty Gamecube controller makes it feel nicer. I think that the parry attacks were a nice addition, because it made fighting certain enemies a lot more fun (Dark Nuts cough cough) and in general was a pretty cool feature.
I've only played TP on the Wii, and I will admit that the basic swordplay aspect is somewhat mediocre. However, the thing that I think makes it better than WW is the hidden skills learned at the howling stones. Those might have been my favorite thing in the whole game. All 6 of them were really fun to use, my favorite being the jump strike. After I learned the jump strike on my first playthrough, I remember just going around Hyrule and using it for fun. In general these were a lot more than a redeeming factor and would like to see this kind of aspect used in future games like it was in TP and with the tiger scrolls in TMC.
