Looking back at past skaters, there are great 3axels for every taste:
Size:
I think Midori Ito and Tonya Harding's triple axels, proportionate to their height, had the biggest 3axels of any skater of either gender. I want to say that Ito has the bigger 3axel of the two, but it's hard to tell from video. Still, Harding's axel lacked Ito's leg wrap, so Harding has the edge in that one area. On the other hand, Ito landed far more 3axels over her career, she even landed one at the ripe old age of 26 at the Japanese nationals (and it was just as huge as it ever was)!
Of course, some men had huge triple axels, too. Jozef Sabovčík had a monstrous triple axel, and that's in proportion to his relatively tall height (he's 5'9", compared to Midori Ito's 4'9"). Given how relatively tall he is for a skater, Jozef's 3axel, where his skates seemed at least clear what would be his waist-level height if he was still on the ice, must've put dents in the roof.
See an example here. Canadian also-ran Vaughn Chipeur had a huge triple axel when he hit it.
See example here. Too bad neither of those skaters had much else going for them.
Intricate entry:
American also-ran Matt Savoie had one of the craziest entries I've seen to a 3axel: he'd do one right out of a hydroblade.
See example here. Among the ladies, Mao Asada used to do her 3axel out of a series of turns, which I thought was both pretty and gutsy.
