The Fiskars is the easier everyday buy unless capacity or reach matters more than effort.
Both loppers are bypass-style, scissor-action tools built for live branches and green wood. The Fiskars PowerGear2 pulls ahead for most buyers because its compound-gear mechanism adds extra mechanical advantage in the middle of the stroke, exactly where a branch resists hardest, so a 2-inch branch takes noticeably less arm effort than a straight-leverage lopper of similar size. Its titanium-coated blade also sheds sap and resists corrosion better than an uncoated forged blade, and at about 3.9 lbs it stays manageable through a long pruning session.
Corona ClassicCUT Bypass Lopper, 36-Inch is still the right call if you regularly cut branches at or past 2 inches or need more reach into a tall hedge or overgrown shrub. Its forged Radial Arc blade is rated for a 2-1/4-inch cut capacity, its 36-inch overall length and 30-1/2-inch hickory handles add real standoff distance, and the blade is resharpenable with replacement parts sold separately. The trade-off is more hand force required per cut since there is no gear assist, even though the tool itself is lighter at about 3.3 lbs.
