I've been employed as a rocket scientist, a landscaper, a rotorcraft engineer, and now an AI researcher, but I will probably be back to landscaping in a year or so.
You can't really be making fun of people for not having a job in this market. #Bidenomics
Shindaiwa was the lightest and was the best imo. The Husqvarna's we had were old and were unreliable to start. One of them had vibrated so bad that whatever heatsink, insulation they had put on it had sloughed off and if you touched it wrong you'd get burned.
If you wanted to weed a ditch you hadn't touched or a month you'd pick the Stihl and turn your brain off. IIRC the Stihl's emissions were worse and it was louder (was way more powerful).
I dunno how well the Shindaiwa's aged though. Being the lightest of the bunch was the most important thing.
One of the Husqvarna's had a converter kit with string trimmer, edge, and then a hedge clipper. Some poor guy (not me, too weak) had to go down a hedge row holding a weedeater above his head trimming the hedges with the hedge clipper attachment. Just miserable.

Those are just landscapers.
There's also an in-between people who call themselves "hardscapers" who do builds/installs of think terraced, rock landscapes; stuff you'd find in a dude who spent 100k on his backyard.
And at the upper end you'll have
Turf Management -- golf courses.
Landscape Architects -- large commercial builds
Landscape Engineers -- probably some made up government job that has a civil engineering background.
