They both look like good tools. I like keeping a handful of ties in every tool bag and box I have so they are handy but seldom have my tool handy, the ties usually get cut off with side cutters. I know...I know not very professional. Good choices in your video.
Great vid. have never used one but that nice flush cut is awesome. We’ve all reached in and a previous tech left a jagged ass edge for our hand to find. Good one 👍👍
For HVAC most guys use either the Klein one in your video or the malco. I switched from Klein to malco because my Klein one got lost in attic and I wanted to try something different.
