Enlan vs Ganzo vs Sanrenmu vs Harnds, edge holding and grinds

Which one of these companies does the best heat treatment and grinds?Which models cut the best and hold the edge longest?

I an only compare a few Ganzos with Enlans
I use either a Enlan EL01 or Ganzo G727M
The Enlan was kind of a must do because while working I lost the Ganzo
I found it a week later, it had been laying in the wet dirt, I cleaned it, and the Ganzo is still sharp, I did not sharpen it at all, the Enlan needs sharpening now after using it much much less.

Also I have used a Enlan EL06, it is a very nice looking knife but it also needs sharpening now already and that too was used much less then the Ganzos (another Ganzo, the G726M is also still very sharp.)

i mainly use them to cut:
herbs and leaves to eat
trim down the now speedy growing wisteria that produces numerous shoots, and only the fresh young green shoots i Cut when I see a new one going where I dont want it to go

I didn’t find any info on Ganzo 746,but have it on order.Endura clone ganzos are very good,and I like them better than real endura.Had endura but lost it some time ago so I got Ganzo,endura iz just overpriced for what youre getting,aand g10 endura forget it lol.
