Favour timeline — who owns each window

StageFavouredWhy
Level 1JayceYou take Cannon-form Shock Blast at level 1 and out-range a melee Jax with no Counter Strike yet -- free gate-Q poke on every last-hit step-up.
Level 2Even / skillYou add Acceleration Gate for the full accelerated orb, but Jax also has his early points and dodges with Counter Strike -- the poke edge is real yet genuinely contestable here.
Level 3JaxJax's Counter Strike comes online: one mistimed gate-Q in auto range lets him dodge it, recast E to stun, and Leap Strike + Empower for the all-in.
Levels 4-5JayceYou still own the pre-item poke war -- both stances online, his items absent, so trade around his Counter Strike cooldown and stack the health lead.
Level 6JaxLevel 6 is a non-spike for you (the stance swap is not a new ult) while his R is a real burst of resists and on-hit damage -- any all-in he survives now is his.
First itemJaxHis Trinity Force or Blade of the Ruined King plus R lets him eat the orb and stat-check you -- your squishy first-item frame loses the extended duel.
Two+ itemsEven / skillTwo items in it is a knife-edge: your banked early lead versus his hard on-hit scaling decides it, so the game must already be ending on your terms.

Early game (levels 1–5)

Cannon-form Q is your whole opening -- take Shock Blast at level 1 and gate-Q his step-ups before Jax has Counter Strike to answer you. The moment you hit 2-3, the accelerated orb through Acceleration Gate plus the cannon-swap first-hit Armor/MR shred chunks anyone who walked up to last-hit, so make him choose between farm and face. The one trap: at level 3 his Counter Strike is up, so never throw a lazy gate-Q from inside his auto range -- if he dodges it and recasts E to stun, his Leap Strike + Empower is on you instantly. Poke from max range, swap to Hammer only to Thundering-Blow a committed leap out of range, then swap back to re-poke.
