I don't think this is instead of, this is as well as. The high tackle framework is very specific in that it focusses on attempts to tackle, or foul play around it (ie attempt to wrap or arms tucked) - so you can use it and get to the same place. This I think is contact with the head outside of that, so ruck, open play, ball carrier forearm fend etc.
Broadly if you use this instead you get to the same place (I would argue a tucked arm / shoulder charge to the head is reckless foul play so no mitigation here, straight red) so you can probably get away with mostly using this instead, but unless told not to I'll use the one that most specifically suits
