I’m not sure what your criteria is, but mine is to keep the grass alive and provide root structure for my soil.
My Luba 2 has saved me 3 weeks of manual mowing over the past year and my lawn has never looked better. Frequently complemented by others.
It's just a lawn and a lawnmower. I'm not playing keeping up with the jones, hoa bullshit or whatever other nonsense Americans invent. It's just a Scottish garden for the wildlife to roam in.
