Is a 2-cycle or 4-cycle gas hedge trimmer better?

2-cycle engines (Echo HC-2020, Husqvarna 322HD60, 122LKH) are lighter and simpler but require mixing oil with gasoline. 4-cycle engines like the Senix 4QL run on straight gas, which Home Depot verified-purchase reviewers repeatedly flag as the main selling point, at the cost of a heavier head and slightly more complex maintenance. Pick based on whether you'd rather mix fuel or carry extra weight.
