Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

EGO Power+ ST1623T 16-Inch Line IQ 56V comes out ahead by a clear margin (4.7 vs 4.2). The gap is mostly about Suburban homeowners with 1/4 to 1 acre who want gas-class power, hate refueling, and don't mind a heavier tool for the convenience of auto line feed. — read the strengths below before deciding.

EGO Power+ ST1623T 16-Inch Line IQ 56V

4.7

$329

The EGO Power+ ST1623T pairs a brushless 56V motor with auto-feeding Line IQ and the brand's POWERLOAD spool, so most owners go a full season without ever touching the head. Pro Tool Reviews ran it for over an hour on a single 4.0Ah pack and scored it 9.7/10. The trade-offs are a 12.6 lb working weight and a price north of $300, but for a homeowner who wants gas-class performance without the maintenance, no other cordless trimmer sweats this combination of cutting width, ergonomics, and warranty.

Strengths

— 16-inch swath with Line IQ auto-feed eliminates the bump-feed dance
— POWERLOAD spool reload takes under 30 seconds with the included pre-cut line
— Telescopic carbon-fiber shaft carries a lifetime warranty

Watch-outs

— 12.6 lb working weight is on the heavy end of cordless picks
— Line IQ can shed string faster than it feeds when trimming hard fence lines
— Recharge time stretches to roughly 70 minutes on the standard 320W charger

Ranked #4 in Best String Trimmers

Worx WG170 GT Revolution 20V 12-Inch

4.2

$129

The Worx WG170 GT Revolution is the best value-tier cordless trimmer for owners of small flat suburban yards who care more about ease and weight than raw cutting power. At 5.5 lb with battery clipped on, it's roughly half the weight of the EGO ST1623T or Ryobi 40V picks above, and it converts in seconds to a wheeled edger or even a mini-mower. The trade-offs are real: T3 noted it chokes on anything thicker than quarter-inch growth, and the 12-inch cutting width forces more passes. For under-quarter-acre yards with maintained grass, none of that matters and the lightness and 3-in-1 flexibility win the day.

Strengths

— Just 5.5 lb working weight makes it the easiest pick on the wrists
— Three-in-one design converts between trimmer, in-line edger, and mini-mower
— Command Feed dispenses line at a button push — no bumping required

Watch-outs

— 12-inch cutting width is the narrowest of any pick here
— Battery life around 30-45 minutes on 4.0Ah pack falls short of larger-format competitors
— Cutting power stalls in anything thicker than light grass or quarter-inch weeds

How they stack up

EGO Power+ ST1623T 16-Inch Line IQ 56V

Outclasses the Worx WG170 GT Revolution on cutting width (16 in vs 12 in), runtime, and build, but you pay nearly triple. Sits below the Husqvarna 525L on raw cutting torque in heavy weeds but matches it on noise, fumes, and warm-up time.

Worx WG170 GT Revolution 20V 12-Inch

Just over a third the weight of the EGO ST1623T (5.5 lb vs 12.6 lb) and a quarter the cost. Forfeits the cutting width and runtime of the Ryobi RY402110, but the 3-in-1 conversion (trimmer / edger / mini-mower) is something none of the other picks here offer. Lighter and quieter than the Black+Decker GH3000 corded pick but with the cordless freedom.
