Favour timeline — who owns each window

StageFavouredWhy
Level 1Even / skillLevel 1 is a genuine standoff — your Q chip damage and his base durability cancel out; neither side has the tools to force a trade yet.
Level 2SionSion's Soul Furnace shield comes up at level 2 and absorbs your W poke burst while his Decimating Smash is a kill threat you have no answer for without E.
Level 3SionFull kit Sion wins the extended trade: Roar of the Slayer shreds your shields, Soul Furnace absorbs your Q burst, and a landed Decimating Smash means flash or death.
Levels 4-5Even / skillNeither side spikes dramatically — you accumulate fragments through W pokes and he stacks Heartsteel; both are building toward their real power rather than fighting for the lane.
Level 6SionDemonic Ascension gives you drain but Sion's Unstoppable Onslaught plus zombie passive mean he can kill you on the way out; this window belongs to him on threat alone.
First itemSionSion's first tank item makes your W poke chip damage and his Soul Furnace shield near-impenetrable in a 1v1; your carry threat is team fights, not this lane.
Two+ itemsSionTwo-item Sion is a walking fortress that your Demonflare nova cannot burst through; your win condition has fully shifted to team-fight drain and objective pressure.

Early game (levels 1–5)

At level 1 this is genuinely even — your Q range is real but Sion can walk at you without fear since you have no root yet and his passive durability eats chip damage. The moment he hits level 2 the lane turns against you: Soul Furnace absorbs your first burst of W poke and Decimating Smash gives him a kill threat that forces you to respect range. Your job levels 1-3 is to W-poke from maximum range, never stand in a spot where a full-channel Q can reach you, and accept that you will not win early trades — Sion's shield plus his raw base stats beat your pre-fragment damage output.
