Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillLevel 1 is your worst window with only Q, and Zac trades evenly since Unstable Matter and his slingshot are spells Counter Strike can't dodge — just farm and watch where his blobs drop.
Level 2JaxTaking W at 2 gives you an Empowered Leap Strike all-in — a burst trade Zac's blob sustain can't match if you step on the blobs afterward.
Level 3JaxFull Leap Strike + Empower + Counter Strike online — bait his pulse or Stretching Strike, leap in, and the recast stun lands even though E won't eat his spell damage.
Levels 4-5JaxRanking the combo keeps your dodge-stun up more often; deny his blobs after each trade so his passive sustain never refills the gap.
Level 6JaxGrandmaster at Arms' armor-MR steroid plus the every-third-hit on-hit ramp turns the extended duel into a clean kill, and you can stand on the blobs he drops.
First itemJaxTrinity Force compounds your stat lead — Zac is a tank with no scaling carry to punish you, so force every all-in while his Slingshot is on cooldown.
Two+ itemsJaxEven at two-plus items Jax out-duels a tank in the side lane — Zac never out-scales you, so close it before his R becomes a teamfight problem.

Early game (levels 1–5)

Zac trades evenly into you early because his damage comes from spells, not autos — Unstable Matter's pulse and his Elastic Slingshot knockup go right through Counter Strike, which only dodges basic attacks, so don't expect your E to eat his whole rotation the way it shuts down a Nasus. The lever is his passive: every time he takes a poke trade he drops blobs, and if you stand on them he can't pick them up to heal the chip back. Farm level 1 with just Q, take W at 2, and at 3 you have the full Leap Strike-Empower-Counter Strike combo to punish him the moment he steps up to slingshot or pulse.
