Head-to-head
The differences that actually change the buying decision.
The Short Answer
Buy the EGO Power+ ST1521S if you have a larger yard, deal with thick weeds or overgrowth regularly, or plan to build out an EGO 56V tool collection over time.
Where They Match
Pivoting head: both trimmers pivot to a vertical position for edging, a feature not universal at either price point.
Auto-feed line: neither requires manually unwinding a spool to reload line, though EGO's POWERLOAD system is generally considered the more convenient of the two.
Build reliability: both brands have a solid reputation for cordless outdoor power equipment, with ratings volume in the thousands and generally positive long-term ownership reports.
Where EGO Wins
Cutting power: the 56V brushless motor holds RPM through dense growth noticeably better than the Worx's 40V motor, a real difference on anything beyond light, well-maintained grass.
Swath width: 15 inches versus 13 inches means fewer passes across a larger lawn.
Shaft rigidity: the carbon fiber shaft flexes less under load than the Worx's composite shaft, which translates to a more precise, controlled cut.
Where Worx Wins
Included batteries: two 2.0Ah packs versus the EGO's single 2.5Ah pack, useful for back-to-back yard tasks without a mid-job charge wait.
Weight: under 5 pounds versus roughly 8 pounds for the EGO, a real factor on longer sessions or when edging at an angle.

FAQ
Common questions
Which is better for thick weeds, EGO or Worx?
The EGO ST1521S, clearly. Its 56V brushless motor holds line speed through dense growth that noticeably slows the Worx WG183's motor. For anyone dealing with regular thick weeds or overgrown patches, the EGO is the stronger choice.
Is two batteries better than one larger battery?
It depends on use pattern. Two 2.0Ah batteries, as included with the Worx, let you swap packs mid-job without waiting to recharge, useful for back-to-back yard tasks. A single larger battery, like a step-up EGO pack, delivers more sustained runtime without needing to stop and swap. For most residential yards, either approach covers a full session.
Is the EGO worth $70 to $100 more than the Worx?
For larger yards, thicker growth, or buyers planning to add more EGO tools over time, yes. For a small to medium yard with typical grass and light weeds, the Worx covers the job at a lower price, and the EGO's extra power goes underused.
Which is lighter to use?
The Worx WG183, at under 5 pounds versus the EGO's roughly 8 pounds. The weight difference is noticeable during extended sessions or when working at an angle, such as edging or trimming a slope.
