I remember watching a Game Theory about this discussion, or did I at the very least saw it and
immediately absconded from the recommended videos section...
IN ANY CASE, I think that the "strongest Link' would probably be the Spirit Of The Hero.
Y'know? That thing that exists in each and every Link, and is basically the thesis of what each and every Link should be?
In short, all the Links are, in my humble opinion, equal because they all exist because of the same spirit that at one point in time flowed through their veins.
To answer your question of "which Link do I like the most", I like Wind Waker Link the most, or Toon Link as Smash dubs him..
Toon Link had a very enjoyable adventure in my opinion and overall is a fun character, plus his character development from a lazy kid on Outset Island into the Hero of Winds made for one of the best story lines I've experienced in a Zelda game, it's admittedly similar to Ocarina of Time Link's journey too.
