what do you mean?
tryndamere farms much faster, turns on earlier in the game and can actually beat susan in trades with lucky crits, W debuff and spin away if he gets withered.
its the same concept as jax really, who does it even better because he can double hit on demand. farms faster, turns on earlier, and AA+W trades eventually going into ult proc + W trades just make it hell for susan.
Does Tryndamere have a better early game? Undoubtedly.
Except Susan shouldn't really give a shit about that. If he's looking to pick a fight with Tryndamere or if he's allowing random cheap shots with his Fury-based crits, then he's quite frankly doing it wrong. Susan's perfectly content on indefinitely lazying about in top lane not getting killed by Tryndamere, rushing tankiness items (read: Frozen Heart above all else) and being able to fight back if Tryn does commit to one from mid-game onwards. Only to never lose that ability thanks to his stack mechanic. Run away from a bad brawl? Unless you're spinning over a wall, Susan's gonna getcha. Proxy farming? Too bad, Susan no care with his lifesteal and that's an advantageous trade for the dog anyways. Roaming or teamfighting? As a non-fed Tryndamere who couldn't push top tower down against a laner who's bound to pick Teleport too? Good luck with that.
Tryndamere's whole shtick is outscaling his enemy if they go for a "nothing but tankiness late game wet noodle" strategy through Renekton, Malphite or Shen (just a few examples) while relentlessly pressuring top lane because those very picks are unable to do anything to stop him once he reaches his item goal. Nor can they quickly push back lanes thanks to their misguided plan. Said players generally misjudging his early damage also plays a huge part in his snowballing and if that happens, he can walk up to anyone who's looking to put a stop on his antics and kill them outright 1 v 1. Susan has none of those flaws; he
could freeze the lane for however long he pleases, can react elsewhere on the map with Teleport (good ward coverage helps too), has Frozen Heart + Wither (and Ninja Tabi + Doran's Shield for overkill), removes a pushed lane out of the picture with Spirit Fire if he's in a hurry and can still dish out the pain with a farmed-up Q.
The only way I can see a Tryndamere walk all over a Susan, is if he lacks common sense. Like using Teleport to exclusively get back in lane on top of wasting his own time by rushing shitty items like Sunfire Cape or Triforce. The latter is a fantastic item in itself, but dowright terrible to rush in this particular scenario.
(Lane Udyr also consistently beats Tryndamere in a straight-up 1 vs 1 if both are left unattended, by the way.)
